i have been the same weight for years and years, it might go up and down by a few pounds, but ive gained 5 pounds and it hasnt gone back down which i know 5 pounds isnt alot but its very different for me. ive been constipated, and my boob has hurt, right around my nipple. i had a period last month but it was shorter than normal. im not expecting a period til the end of the month. but is it possible those are signs of being pregnant? can you have a period and still be pregnant?
