I took bc for 6 days, at different time frames and suffer from diarhhea during this time. I started the birth control on the third day of my period and had a 5 day period. I had unprotected sex the day after stopping bc where I had my last pill previously at 11am. I didnt take any further pills in hopes to conceive, because that was my fertile week. Is this possible? How long do I have to wait before taking a pregnancy test? 28 days after break through bleeding or a week after when my normal period is suppose to arrive?
