boobs are a little sore on the sides. they look more round and firm. my stomach is more round looking and hard feeling in the lower part can't push it in like normal. and feels like there's a dip in the middle of my lower stomach when I run hand across. been having a big appetite lately. could this be from eating alot or possible pregnancy ?
