If you experience breakthrough bleeding on the pill, it does not mean that you are pregnant. If you are taking your pill correctly each day, the hormones in the pills prevent you from getting pregnant, even if you are experiencing breakthrough bleeding.

Is breakthrough bleeding common in early pregnancy?

Bleeding during early pregnancy is common

About 1 in 4 people experience spotting during early pregnancy, usually in gestational weeks 5 and 8 — this is about 1 to 4 weeks after someone expects their period (1). This bleeding can sometimes be confused with a light period (2).

How do I know if its breakthrough bleeding or implantation bleeding?

That said, breakthrough bleeding can occur at any time, and implantation bleeding only happens a few days before a missed period. The best way to tell if you're experiencing implantation bleeding is to either take a home pregnancy test or visit your doctor for a blood test.
