So I was taking a bath earlier and started feeling thumping in my lower belly, what was even more weird is that I could see my stomach move when the thumping would happen.... my last period was October 10th... I had 2 days of light bleeding the last week of november and took a pg test, it was negative, I have not taken one since... my husband thinks it was gas... but today is the first time I've ever felt it, and I could literally see my belly move with every thump... idk what it could be, any ladies experience this? Gonna take a pg test tomorrow. Just curious.
