Pre-pregnancy spotting: what to know

Spotting is light bleeding between expected periods. It may happen around ovulation, after sex, when contraception changes, or when the cervix is irritated. An infection such as Chlamydia can also cause bleeding, particularly after sex, sometimes with unusual discharge, pelvic discomfort, or burning when passing urine. Polyps and fibroids can affect bleeding patterns. Less commonly, abnormal cervical cells or a womb condition need checking. The pattern does not diagnose the cause by itself.

Record when the spotting began, its colour, how long it lasted, whether it followed sex, and any pain or discharge. If pregnancy is possible, a home pregnancy test and clinical advice can help distinguish pregnancy-related bleeding from bleeding between periods.

Use a liner if needed and avoid putting anything into the vagina until you understand the cause, especially if bleeding follows sex or comes with pain. Keep a simple cycle and symptom record, including contraception, medicines, and pregnancy-test results. Arrange a routine appointment if spotting recurs, lasts beyond the expected cycle change, or happens after sex. A clinician may discuss an examination, infection testing, cervical screening history, or imaging based on your symptoms.

Seek urgent medical help for heavy or rapidly increasing bleeding, severe or one-sided pelvic pain, fainting, marked dizziness, shoulder-tip pain, fever, or feeling very unwell. If you have a positive pregnancy test with bleeding or pain, contact a maternity or urgent-care service promptly because pregnancy-related causes need assessment. Bleeding with unusual discharge or pelvic pain also warrants timely infection assessment.

Could this be related to ovulation, contraception, infection, the cervix, or the womb? Do I need a pregnancy test, infection test, cervical examination, or ultrasound? What changes should make me contact you sooner?
