Hey im 31 weeks, and at night if i just lay down to rest, or in the middle of the night i feel like a constant flow of bubbles popping in my lower belly, almost like i have to fart, tmi, but its not a stomach issue, its too low for that. The baby is still but will move every now and again after so many bubbles. Its a consistent thump in my abdomen and its honestly weird. Any experiences? Any answers?
