I am 23 years old....I have been dating the same guy for a few months now I told him I was not on birth control but he said he wasn't worried about it....I'm supposed to start my period tomorrow or today, I have had all the normal symptoms I do before my period, cramping and moodiness, not that much in the way of craving anything, but felt really nauseous before eating yesterday and overly full and bloated all day and felt like if I did eat I would throw up, now I just want to go to bed. I feel so bloated that There feels like there is pressure on my bladder and I feel like I need to pee. Normally my stomach is fairly flat and I can feel it poaching when I sit which bothers me a lot lol I have also been really constipated this past month. Not sure if this is all due to my period but I keep getting wondering in the back of my mind if I could be pregnant?
