TTC question

Jessica
Hello!! AF is due in 2 days and for the last 2 days my lower abdomen has felt very heavy and I don't want to say sensitive bc that's not the right word... but just a little weird.  Could that be a sign of pregnancy? We've been TTC for a few years now so I don't want to rush into taking a test and get a BFN. My this has never happens before. It's sort of more swollen too. I usually bloat before AF comes but this is pretty noticeable. Any help would be nice!!
