Pink spotting after intercourse

Christina
Boyfriend and I had intercourse this morning at around 11am- I just noticed pink spotting at 5pm. It's very slight and my cramps have not intensified since then (same cramps I've had all week). I am 5 weeks and 2 days pregnant. I've heard that spotting is normal after intercourse because of the extra blood flow and cervical swelling but I just wanted to ask around to ease my mind.
