So lately I've been having a lot of pregnancy symptoms, but I'm still getting my period once every 2-3 months (which is sometimes normal). I'm really doubting the possibility and am currently looking for what else it could be because the last time I had unprotected sex was 7 months ago(any sex at all was 5 months). More in depth symptoms include but not limited to: nausea, cramps, bloated feeling, backache, headaches, fatigue (really would just sleep all day if I could) lightheadedness(is that a word?), and that's just off the top of my head. I would really appreciate any answer as to something else this could be.
