According to the app that tracks my period, yesterday, 13th april, was my ovulation day. But I lost track and had unprotected intercourse that night. My boyfriend withdrew just before ejaculation, but I have a doubt about him pre-ejaculating inside of me. Hence, as a precaution, the next day i.e. 14th april I took a pill (mercilon). After taking the pill, i had a little vaginal bleeding, red-brown(ish) thick mucus type. Also, I've read about implantation bleeding. Could I be
pregnant? Should I take a UDT now itself?
