I had such bad gas and couldn't fart then after Awhile I went number two and (tmi but) as soon as it came out I farted for like a minute straight lol
A lot of yoga moves help! Google to find them. But I had horrible gas before I was pregnant and after, it just got worse. So I asked my doctor if she'd be ok with my taking gas-x, and she okayed it. Ask your doctor about some medicine if you want!
