OK mom's I have a Questíon just yesterday my stomach and legs were itchy seriously itchy so thought you know maybe it's just my skin stretching so I took a shower then moisturized my skin it was still itchy so me being the person I am I had to itch and this morning I noticed bumps on my stomach like I was being bit but there were two different bumps some looked like they were turning red and the others looked like huge bubble bumps that hurt to the touch should I be worried?
