Need help!!!!!

What does this look like I’m 38 almost 39 weeks pregnant. Had a similar rash like this earlier in my pregnancy but it went away after like 4-5 days. Only 1 sexual partner which is the baby dad and he hasn’t ever been with anyone else nor have I. It’s on my inner thigh where I usually get rashes from the heat cuz I’m bigger and my legs rub together a lot plus it’s hot so I sweat a lot more now.

Update:

When to my doctors she checked it out, was nothing more than a heat related rash and told me to use a 1% Over the counter steroid cream to help it and it’s gone away completely besides a bit of discolouration.
