Blood inside condom

So long story short... My boyfriend and had sex. We didn't use a condom for a little bit and then he put one on. After we were done, he went to the bathroom and there was blood in the condom. So I went to check and see if I was bleeding and I was just a little bit. It was like a pinkish red color. The next morning I woke up and AF had came. Is that normal and should I be worried about anything?
