I took my last pill on Thursday, and missed Friday, Saturday and Sunday this week. It is now Sunday night. I had sex with my boyfriend Wednesday, Thursday, Friday, Saturday and Sunday morning. I have now started bleeding after three days of not being on the pill which I think could be my period. I was meant to start my period tomorrow, is it likely I am pregnant? Also do I carry on taking the pills I've missed or have a period and if so when do I start taking pills again?
