i usually have omaprezole for my acid reflux and the doctor wouldnt give me them cos i was preg, they would only give me gaviscon and said they wont prescribe anything else for stomach stuff during pg. as a former bulemic i can say that bleeding when throwing up is only usual if you have vomited to excess repeatedly in a short space of time, u get clear fluid as there is no food and it is basically saliva, u can get yellowish bile occasionally or small amounts of blood, usually bright red or pinky. darker blood or large amounts are something to be very concerned about as they could be a rupture or anything in your stomach, intestines or eosophagus.
