I am very bloated, started birth control around a month ago. stomach round and sticking out. normal? or is there something else that could cause it?

Could be frmm thator: Could be form something else like an ovarian cyst , i would recommend a pelvic ultrasound and to blood check kidney and liver function, assuming all of that is normal which it probably will be then it is most likely from pill , and if it does not go away on second pack or gets worse u may need to stop or drop down to a lower dose if u are not already on the lowest dose, loloestrin lowest pill.
