Could I be pregnant?

Is it possible to be pregnant even if you got your period previously? My bf and I had sex with a condom because im not on birth control but it broke within a few minutes. I know we shouldn’t have but we did, we kept going without the condom and he pulled out and then a week later he left (because he’s in the military) and I got my period the next day. So I got my period a week after we had un protected sex. Now far forward it’s been a month and two weeks ago my discharge was pinkish and I was so confused but I let it go and it was only once. Back to today, I’m 3 days late and I don’t know why :(
