3months ago i was afraiD

i could be pregnant because my period was late 2 days but then it came normal flow and has been comming ever since. so i guess it was stress because i didnt do a test. now maybe im still paranoid or what everr but my stomach seems a bit firmer. not under belly bottom. and i cant suck in my belly as much as i could before. i have been dieting. also i have very slow BM sometimes i stay 7-10 days with out going to the bathroom #2 i have always been like that. anyways QUESTION FOR THE MORE CHUBBY WOMEN what you try suck in your stomach and press on it does it feel hard?? IM SORRRY FOR ASKING THIS RANDOM THING I AM JUST TRYING TO UNDERSTAND. I HAVE AN APPOINTMENT WITH THE GYNECOLOGIST NEXT MONTH.
