Basically my whole pregnancy so far (15 weeks) I've had this rash on both sides on my hips. Wtf is happening?

It's itchy, I've just told myself it's because I'm stretching but i don't see any stretch marks and it is only in these places. I've been doing anything i can for them, just forgot to ask my obgyn about it at my appt yesterday. Won't have another appt for 5 weeks.
