I have been on the Pill for 4 months now. I had unprotected sex twice in the last week (aka he came inside me). I take my pills everyday around the same time. I started my inactive pills yesterday on Sunday, had Unprotected sex on Friday and Saturday. Normally I don't start my period till Monday-Tuesday. It's Monday morning and I still haven't started but I'm having some symptoms.What are my chances of getting pregnant in these circumstances? If I have a my period will this mean I'm not pregnant?
