I am 27 weeks pregnant, is it normal that my stomach turned blue on me?

Your stomach turned blue? Can you give more details please?

I was in the tub and mi back started to hurt so I sat up and seen mi stomach was turning blue. So I got up really quick and it took like 5 minutes then my stomach turned back to the normal color but the whole thing turned blue on me.

First please don't use the Comments feature for followups. Use the Answer options instead. A bluish tint to skin usually means that blood flow has been interrupted to the area. If it quickly returned to normal it should be OK, but I would certainly make an appt with your OB/Gyn to have it checked.

If it was just a tinge of blue I had the same thing when pregnant, it just seems like its taking longer to circulate round that area, but I would speak to your midwife hun
