I am 7 weeks pregnant, and I am really having trouble at night with gas, heartburn. It's almost like the gas moves to my chest when I lay down for bed (even after waiting 3 hours after eating) causing lots of pressure along with heartburn. Which wakes me up at night, causing diarrhea and a little vomiting too. This has been nothing like my last pregnancy with my son(he's 2). I almost have to sleep in the guest bedroom to prevent disturbing my husband at night with all the bathroom trips, please help!!!
