a little blood after first sex!

Olga
Hey ladies, I found out I'm pregnant 5 days before period was due...today is one day after period was due and I had sex for the first time since finding out. I'm 4 weeks and 2 days. When I wiped myself afterwards there were two or three spot of blood...Then after I peed another small spot. Is this to be expected? I didn't have implantation bleeding or any brown spotting at all so far.
