I have been prescribed Amoxicillin for 10 days twice a day and have been on birth control specifically Ocella for a year and couple months and I take it religiously. Never miss a pill. Well I started tje antibiotics on Wednesday 2/25 and had unprotected sex Friday 2/27 my husband pulled out but doesnt know if anything leaked or not before that. I take my ladt birth control pill today Sat 2/28 and suppose to start my period Wed 3/4 - Sat 3/7. I usually spot wednesday and thursday and have the full on period either friday and saturday and start pills again on sunday. Im just wondering if I need to go get the morning after pill at this point or if there is even a possibility for me to be pregnant?
