For the past few months I've had lower back pain, random heartburn and digestive issues. I just noticed the other day that my belly looked as though it was pudging out..my instinct goes to it just being acid reflux or something because I've suspected I've been pregnant for a couple months but I have had my period every month and it's been normal.. But I can't shake the thought of it being pregnancy (because I've heard some women bleed through pregnancy) anyone have any advice?
