Period or pregnant?

So my periods are usually a bloody gory mess... But this “period” came 3 days early on Saturday night. There was some slight spotting but literally nothing. This is the most blood I’ve gotten since Saturday night...

Could I be pregnant?? I should also add that my husband was gone for 2.5 weeks for Annual Training for the Army and before that we only had sex 2 times before he left.

We’ve been trying to have another baby since last August.

Has this happened to anyone else??
