I have a slight pee like odor i notice mostly after sex. but sometimes throughout the day. i also just had a baby a month ago via c sec what can it be?

Here are some ...: What you described could be normal as long as being comfortable without other UTI-/STD-related symptoms and such (offending?) odor fades expectantly in one day. Known to most if not all, the odor of semen and vaginal fluid is personally unique, especially after their mixing. So, it's okay and try not to be over-conscious about it.
