Spotting after intercourse

So I am 5 weeks and 3 days pregnant with my second child. I had a miscarriage back in August of last year. My husband and I had intercourse earlier and immediately after when I wiped I was spotting. It wasn't heavy or dark in color, but it was enough to make me nervous. From everything I have read, it seems to be normal but I was wondering if anyone else has gone through this and has any advice. Thanks in advance.
