I'm on the mercilon family planning. i've had my period 11-16 july and then again 01-06 august (i'm still spotting a bit) is this normal? 2nd period is way too early.

Spotting on BCP: Spotting and irregular breakthrough bleeding can occur with BCP especially the first few months and though it reduces the risk of pregnancy there is a small risk. Would check HCG and discuss the breakthrough bleeding with your doctor. https://www.netdoctor.co.uk/medicines/sexual/a7082/mercilon-ethinylestradiol-and-desogestrel/
