I'm 20 weeks and 1 day today, but for some reason I've been VERY gassy all day. It's odd, didn't really eat anything different either but I do t like to..fart so I just let them pass n hold them in, I know tmi but is this really bad for the baby? And also I was sitting on the edge of a bed n went to lay back and its painful on my belly and lower abdomon. Could this be from the gas or what?
