Track Spotting Between Periods
Spotting is light bleeding outside your period: a few drops of red blood, or pink or brown discharge, often only noticed on underwear or toilet paper and usually too light to need a pad or tampon. It is very common and frequently harmless, for example around ovulation, in the first months of a new contraceptive or in the years before menopause. But bleeding between periods is also one of the signs doctors ask about first when looking for polyps, fibroids, infections, cervical changes or a pregnancy, so when it happens and how often matters. A precise record of the days you spot, where they fall in your cycle and what came with them turns a vague 'I sometimes bleed between periods' into a pattern you and your doctor can actually read.
Why track this symptom?
- See where spotting falls in your cycle: mid-cycle around ovulation, in the days before your period, or at random.
- Keep spotting apart from your real period, so your cycle length and next period stay accurate.
- Give your doctor dates, frequency and triggers such as sex or a new contraceptive, instead of a memory.
How Trace Health helps
Trace Health logs Spotting in one tap, separately from Period Flow, so a day of light bleeding never starts a new cycle or shortens your cycle length. Each day you spot shows as a pink dot under the cycle bars in your cycle views, so you can see at a glance whether it lands mid-cycle, just before your period or anywhere at all. After a few cycles, Trace compares Spotting with your cycle like every other symptom and tells you if it tends to appear before your period, as it starts or around ovulation, marked Likely or Possibly. With Apple Health Export on, Trace saves your spotting to Apple Health as intermenstrual bleeding, and with Import on (Premium) it brings in spotting logged in the Health app or in a period app that saves to Apple Health. Log a new pill, a missed dose or sex alongside it, and share a PDF report with your gynecologist.
Common causes
The most common cause of spotting is hormonal contraception. Breakthrough bleeding is expected in the first three months of the combined or progestogen-only pill, the patch, the ring, the injection, the implant and the hormonal IUD, and it is also triggered by missed or late pills, vomiting or diarrhea that stop a pill being absorbed, and some medicines such as certain anti-epileptic drugs or St John's wort. The copper IUD often causes spotting and heavier periods in the first months. Ovulation spotting is a short, light bleed mid-cycle when estrogen briefly dips. In early pregnancy, light implantation bleeding can appear around the expected period. In perimenopause, ovulation becomes irregular and cycles shorten, lengthen and spot. Structural causes include endometrial and cervical polyps and fibroids, especially those growing into the uterine cavity, and adenomyosis. Endometriosis is linked to premenstrual spotting, and PCOS to irregular, unpredictable bleeding. Thyroid disorders and high prolactin can disturb the cycle. Cervical causes include cervical ectropion, which bleeds easily after sex or a smear test, cervicitis and, rarely, cervical cancer. Sexually transmitted infections such as chlamydia and gonorrhea commonly cause bleeding after sex or between periods. Vaginal dryness, which is common in perimenopause and while breastfeeding, can make sex cause light bleeding. Stress, intense exercise, significant weight change, emergency contraception, HRT and blood thinners can all play a part.
When to see a doctor
See a doctor about any vaginal bleeding after menopause, meaning after 12 months without a period, even a single spot of pink or brown: it always needs checking. See a doctor too if spotting between periods keeps happening over two or three cycles, if you bleed after sex more than once, if spotting is getting heavier or turning into bleeding that needs protection, or if bleeding continues beyond the first three to six months of a new hormonal contraceptive or HRT. Take a pregnancy test if there is any chance you are pregnant, and get bleeding in pregnancy checked. Seek urgent care for heavy bleeding (soaking a pad or tampon every hour for several hours), bleeding with severe or one-sided pelvic pain, shoulder tip pain, dizziness or fainting, or bleeding with fever, unusual or foul-smelling discharge or pain during sex, which can point to an infection. Keep your cervical screening up to date. Bring your Trace Health log: dates, cycle days, color and amount, and anything that came before it.
Frequently Asked Questions
Is spotting between periods normal?
Often, yes. Light spotting for a day or two around ovulation is common and comes from the brief dip in estrogen around the time the egg is released. Spotting is also very common in the first three months of the pill, patch, ring, implant, injection or a hormonal IUD, and after a missed or late pill. In the years before menopause, irregular cycles with occasional spotting are expected too. What makes spotting worth a doctor's look is the pattern rather than a single episode: spotting that keeps coming back cycle after cycle, bleeding after sex, spotting that is getting heavier, or any bleeding when you could be pregnant or after your periods have stopped for a year. A log of dates and cycle days is the quickest way to tell which situation you are in.
What is the difference between spotting and a period?
A period is a flow: it builds over the first day or two, usually needs a pad, tampon, cup or period underwear, lasts around three to seven days and comes roughly every 21 to 35 days. Spotting is lighter and shorter: a few drops or a pink or brown stain, often for a single day, with no real flow. Brown discharge is simply older blood that took longer to leave the body. The distinction matters for tracking: if light bleeding is logged as a period, your cycle length, next period estimate and fertile window are thrown off. That is why Trace Health keeps Spotting as its own symptom, separate from Period Flow, so it shows up in your cycle without ever starting a new one.
Can spotting be a sign of pregnancy?
It can. Some people notice light spotting around the time their period is due, roughly 10 to 14 days after conception, often called implantation bleeding. It is usually lighter and shorter than a period. Because it is easy to mistake for a light period, take a pregnancy test if there is any chance you could be pregnant and your bleeding is unusual or your period is late. Bleeding in a known or possible pregnancy should always be checked by a doctor, and urgently if it comes with one-sided pelvic pain, shoulder tip pain, dizziness or fainting, which can be signs of an ectopic pregnancy. Trace Health does not detect pregnancy; your log simply gives the doctor the exact dates.
Why do I spot a few days before my period?
Light brown or pink spotting in the one to three days before a period is common and often reflects falling progesterone at the end of the cycle. When it happens every cycle, lasts several days or is getting longer, it is worth mentioning to a doctor, because premenstrual spotting is also associated with endometriosis, endometrial polyps, fibroids and a short luteal phase. After a few cycles of logging both Spotting and Period Flow, Trace Health checks whether your spotting gathers in the week before your period. If it does, Spotting shows a pattern such as 'Starts in the week before your period', and the What to expect card can warn you in the days ahead, which also gives your gynecologist a clear, dated pattern.
Does Trace Health sync spotting with Apple Health?
Yes. With Apple Health Export turned on, every Spotting log is written to Apple Health as intermenstrual bleeding, next to your periods, so other apps you allow can read it. With Import turned on (Premium), Trace brings in spotting logged in the Health app, on Apple Watch or in a period app that saves to Apple Health. Imported spotting comes in as Mild, and consecutive days of spotting are grouped into one episode, so a three-day stretch reads as one event rather than three. Your data stays on your iPhone and in your own Apple Health, and imported spotting is included in the same cycle insights and PDF reports as the spotting you log in Trace.
