I had sex yesterday and he told me that he had cum. Afterwards there was no cum in the condom, but then he came about 10 mins later onto my hand. I'm not sure if it was possible that he came inside me or not but I decided that tomorrow I should get the morning after pill. However, I think I might be on my period tomorrow. What i want to know is, if I have my period tomorrow, is there any way I could still be pregnant from having sex last night?
