Are rashes normal to show up

At 7 weeks, I have been experiencing rashes everywhere in my body. It started to show in my inner thighs. Then I noticed having rashes around my armpits and arms. I consulted my OB about this and she just advised me to put a topical cream (Elica) on the rashes. Now, at 8 weeks, the rashes seemed to subside, but it showed up somewhere else (like on buttocks, legs). It was mostly showing around my pelvic area (bikini line area). Also, smaller rashes (somewhat like dot size rashes which are itchy) show up on my thighs and back. Not sure if this is normal. Has anyone experienced the same thing? Thanks in advance.
