We used a condom but really nervous?

So me and this guy(not quite my bf yet but we have a history) had sexalmost a week ago and I am due for my period any day. It was both our first time and we used a condom but nothing else. He said he didn't know if he came but you could see sperm in the condom. Being it was my first time I didn't check for breaks or anything and now I am really scared that I am going to be pregnant. Waiting for my period is killing me becaus every day I dot get it I think I might really b pregnant. Im starting to freak out and wonder if some sperm might have leaked Out the top or it might have broken and we didn't know it. I do no that we didn't do anything before he put the condom on and it was new. Is there anyway I might b pregnant!?!?!?
