Ok i need all your thoughts on this. I had my time of month on the 29th of may but for the past couple of weeks my stomach has been changing in the sense that it has been a lot more hard/firm and it has never been that way. Ive also gained weight. The only thing in my diet that has changed is ive been taking prenatal vitamins for the last month but i read that cant make you gain weight. What do you guys think? Can i still be pregnant?
