light spotting.

Kayla

So, I'm not sure if this is the right group to put this in. (I'm sorry if it's not)

My honey and I had unprotected sex 3 days ago and now I'm having very light spotting that's redish/pink. I was supposed to start my period today, but it's normally not light at all. So I'm not sure what it could be? Could it be a sign of pregnancy?
