Rash on stomach - should I be worried??

[Morningnewspaper]

I noticed a rash all over my belly yesterday - not itchy and quite red and blotchy in nature. If I rub it, it feels slightly burny. No bumps. Now 3 days ago I started using baby oil after a shower all over my body and I wondered if it might be that, so I didn't use any this morning. The rash seems to be covering more of my skin now. I am assuming that this is a harmless hormone related pregnancy rash. has any one else had anything like this? I'm 11 weeks.

It might not be anything to worry about but there is something called Obstetric cholestasis or something like that so my spelling might be off, get a midwife app just in case. It could well be nothing but i know i would want to know. Good luck and i do hope all is well.
