confused....

Nichole
So I found out at the beginning of January I miscarried at six weeks. I then finally got my period back February 1st thru the 5th and it was medium to light flow.  The last couple times I've gone to the bathroom today I've been spotting. It's not heavy but I don't know if I should worry. I don't mean to sound dumb. We have had unprotected sex and not pulled out. Idk if that means I could possibly be pregnant or my period again.  Again I don't mean to sound dumb but any advice would be helpful.
