Post partum

did anyone had part partum rashes?How long did this rash lasted? I had post partum rashes during confinement but I didn't see Dr then after few weeks it gone off by itself. Now I'm post partum going 3 months but I had rashes but the Dr could not conclude what is the cause but high chance is post partum rash. My rash is coming two weeks but now I can't really go out to see Dr as I'm the sole caregiver for my baby.
