Ibs sufferers and pregnant

Few days ago I got some pains on my right side lasted for a few days, I've been feeling nauseous...went to the Drs and he said I have IBS....i had IBS years ago and never really suffer from it untill now? Has anyone else heard of an IBS flare up and got a bfp??I'm quite warm and tender breasts and extremely emotional more than usual I've cried 5 times today for no reason
