I just had my period a couple weeks ago. Before the 4th of July. My fiancé and I have been having unprotected sex for the past week and a half. Now yesterday and today I have been experiencing some light bleeding/spotting and yesterday I had cramping. My period isn't due for another week or two. Could I be pregnant, or is it just breakthrough.

Also, yesterday the bleeding was really light, like a pink. Today it was more red. If that makes any difference at all.
