So my last period was around the 15th March I know this as I had my exam that day, around the 8th of aprilmy boyfriend came inside me and he did the next day on the 12th of April my friend gave me a unopened pack of the pill but I don't even know about this pill as she broke up with her boyfriend and didn't need them anymore I've googled it and there's not much information I've read the leaflet in the packet and it is the pill but there's little information so ive been taken them for 21 days I'm at the end of the pack and my period is 10 days late my boyfriend has came inside of me numerous times while I've been taking it I guess I'm asking what is the possibility I could be pregnant? I've just had really sore right boob and I really tender nipple and occasionally feeling sick pictures attached
