Itchy skin while working out?

Hi everyone! I’m 17 weeks and have noticed that no matter which workout pants I wear, I get EXTREME itchiness around my bikini line, waistline, inner thighs, and hips. I’ve tried my lululemons, cheap amazon leggings, maternity leggings, moisturizing right beforehand, EVERYTHING! Is anyone else experiencing this? Any tips for comfy workout pants?
