Hello. I have had unprotected sex with my boyfriend throughout the month. We are okay with whatever happens. I had some light pink spotting 10 days before my expected period and it lasted about a day and was so light that it was only there when I wiped. (Tmi) sorry. Also my boobs normally get super sore a week before my period and they aren't sore at all if that means anything. I also experienced heart burn for the first time the other day. Could I be pregnant or am I just over thinking?

Yes.

Best to wait until you miss a period. Wait a little more, about 2 weeks, and try a home pregnancy test. Then you should know. There is a good chance that you could be pregnant, but an equally good chance that it's all in your head.
