hi,
im 18 and iv been taking the contraceptive pill, and a while ago me and my bf had unprotected sex. Ever since every now and then i have missed out on taking pills or have been taking them late. Ever since i have had heavy periods with blood clots and have had a creamy looking discharge everyday. This has been going on for a couple of months, and now im worried because before i thought it was normal. Is this a miscarriage?, could anybody help me?.

thanks.
