About a month ago a small red bump that looked like a pimple showed up over night. I tried squeezing it one day and immediately after there was a red rash around it, and I started thinking spider bite. It hurt very badly to the touch, so bad I couldn’t lay on that side when I slept. The pain and redness has been gone for a while now, but I’m worried it’s not getting any better. In my experience spider bites go away within 2 weeks, and now it’s been about a month. I’m worried it may be something else. Anyone had anything similar??

First picture is around 2 weeks when rash showed up

I’m 27 weeks pregnant and getting worried, although I have zero other symptoms other than normal daily preggo symptoms. Anyone seen anything like this??
