How do you prefer to lay? Are you laying on your back or side. It could be the way baby is positioned & the weight from baby is too much. I've been told laying on your left side is best since there are less internal organs for baby to lay on as creating better circulation. I do lay on my right from time to time but my little boy is starting to kick my liver when I do that & it really hurts!
Omg I have the samd problem and im only 23 wks it can be vety scary
