Spotting between periods: common causes and when to get checked
Spotting between periods is light bleeding outside your normal period. A little mid-cycle spotting around ovulation is common, and so is breakthrough bleeding in the first months of hormonal contraception. Other causes include missed pills, an IUD, cervical irritation after sex, polyps, infections and early pregnancy. Bleeding between periods that keeps happening should be checked by a doctor.
Spotting vs bleeding between periods
Spotting is a few drops or a pink or brown smear that a liner can handle. Bleeding between periods (doctors call it intermenstrual bleeding) is more: a flow that needs a pad or tampon. Both are worth noticing, and both have a long list of possible causes, most of them harmless. The pattern matters more than one single episode.
Common causes of spotting between periods
| Cause | What it usually looks like |
|---|---|
| Ovulation spotting | Light pink or brown for a day or two, about two weeks before your period, sometimes with one-sided twinges |
| Starting or changing hormonal contraception | Irregular light bleeding in the first 3 to 6 months |
| Missed, late or restarted pills | Spotting a day or two after the missed pills |
| Copper or hormonal IUD | Spotting is common in the first months after fitting |
| After sex or a smear test | Small amount of fresh red or pink blood, soon after |
| Early pregnancy | Light spotting around when your period is due |
| Perimenopause | Unpredictable spotting alongside changing cycles, usually in your 40s |
Ovulation spotting
Around ovulation, estrogen peaks and then dips briefly. In some people that small dip is enough for a little of the lining to shed, giving pink or brown spotting mixed with stretchy ovulation discharge. It's harmless and usually lasts a day or two.
Causes that need a check
- Infections, including chlamydia and gonorrhea, which can inflame the cervix and cause bleeding after sex
- Cervical or uterine polyps and fibroids, usually benign growths
- Thyroid problems and PCOS, which disrupt ovulation
- Pregnancy complications, such as miscarriage or ectopic pregnancy
- Medicines that thin the blood
- Rarely, precancerous changes or cancer of the cervix or womb lining, which is why persistent bleeding between periods or after sex should always be checked
Spotting on hormonal contraception
Unscheduled bleeding is one of the most common side effects of hormonal contraception, especially progestogen-only methods like the mini pill, implant, injection and hormonal IUD. It's usually light, irregular and harmless, and it often settles after the first three to six months. It doesn't mean the method has stopped working, as long as you're using it correctly. If it's still bothering you after a few months, or starts suddenly after a long settled spell, a doctor can check for other causes (including an STI) and talk about switching methods.
Spotting after sex
Bleeding after sex (postcoital bleeding) is often from the cervix, which can be more delicate on the pill or in pregnancy, or from dryness. But it's also a classic sign of chlamydia and, rarely, cervical changes. If it happens more than once, get it checked rather than waiting.
What to do if you're spotting
- Note the cycle day. Is it always mid-cycle? Always after sex? Random?
- Take a pregnancy test if there's any chance you're pregnant.
- Check your contraception. Missed pills, a new method or a recent IUD fitting explain a lot of spotting.
- Keep your cervical screening up to date. It's one of the simplest protections there is.
- Book a check if it happens for more than a couple of cycles, or with any of the red flags below. Doctors may suggest an STI test, a pelvic exam or an ultrasound.
Two or three cycles of notes on when spotting happens, how much, and what else was going on make the appointment faster and more useful.
When bleeding brings worry
Unexpected blood is unsettling. It's normal to feel anxious, especially if it's new, and that anxiety can sit on top of whatever phase you're in. The good news is that most mid-cycle spotting is harmless, and the cases that aren't are usually very treatable when found early. Getting checked is an act of kindness to yourself, not an overreaction.
See a doctor if you bleed between periods for more than one or two cycles, bleed after sex, have spotting with pelvic pain, fever, unusual or smelly discharge, or pain when peeing. Get urgent help for heavy bleeding, bleeding with severe one-sided pain, dizziness or fainting, or bleeding if you're pregnant. Any bleeding after menopause should always be checked, even once.
Frequently asked questions
Is spotting between periods normal?
Occasional light spotting around ovulation or with a new contraceptive is common. Spotting that keeps coming back, or happens after sex, should be checked.
What causes bleeding between periods without pain?
Common painless causes include ovulation, hormonal contraception, an IUD and cervical irritation. Polyps can also bleed without pain, so recurring spotting is worth a check.
Can stress cause spotting between periods?
Stress can disturb your hormones and ovulation, which can cause irregular bleeding. It's best not to assume stress is the cause until other reasons are ruled out.
Is mid-cycle spotting a sign of pregnancy?
Mid-cycle spotting is more often ovulation. Implantation bleeding happens later, around when your period is due.
