Do I need to go to the doctor?

So I had a baby four months ago and ever since I feel like my natural scent smells different. I’m normally a female to have white discharge often and a lot it’s always been that way with me bc apparently some don’t get it to much.. but anywho, when it first comes down now it doesn’t smell but if I don’t change my underwear and I’m not wearing a panty liner and say I’m at work and don’t have any it starts to smell a little (i know gross) and I feel like it’s terrible to me. I’ve asked my SO and he said he never smells anything.. I’m self conscious now .. should I go see a doctor or is it normal for it to start smelling? I’m a clean person I don’t need judgmental comments please
