I'm about 23 weeks pregnant, my second pregnancy. I've been through the morning sickness etc with both my pregnancies but something has been going on recently; usually as I'm falling asleep I start getting extremely dizzy, disoriented and like I'm on the verge of passing out, then come the extreme stomach cramps. (I'd actually rather go through labour pains than these cramps) they are so painful they make me shake and unable to talk, I rush to the toilet as I start to feel sick and I vomit forcefully until my stomach is empty, and there is a lot that comes up, lots of undigested food etc. Then once that's calmed down, the other end starts and I have the most horrific diahorrea, it's endless and like water and I get the worst shakes like my body has gone into shock. This has happened 5 times now over the past few weeks, a pharmacist told me it sounds like indigestion but I'm not convinced. I know pregnancy can do awful things to your body but this actually really scares me and last time it happened I nearly had my partner call me an ambulance as the pain was so unbearable. Has anyone had this or know what it could be? Thanks so much for taking the time to read and answer!
