So fed up. I'm 18 weeks and had heartburn/indigestion from 6 weeks on the dot. For me it isn't chest pain or anything but acid in my throat and constantly feeling food is coming back up my throat after I've eaten. I'm on 40mg omeprazole a day AND rennies and it helps with the acid but not the feeling of food coming back up and general feeling of yuck. It's driving me demented. I had it in my last pregnancy but not til the third trimester and it was treatable with Gaviscon. Everyone else says omeprazole sorted them right out, it hasn't me.
