29 weeks pregnant and cramps

Hi everyone! I’m currently 29 weeks pregnant and last night within the span of two hours, I had really sharp, take your breath away pains in my lower right abdomen. Didn’t think too much of it

Today since around noon I’ve had pretty constant period-like cramps. I’ve laid down and tried to take it really easy. I called my dr around 3:30. The nurse suggested I lay on my side and drink as much water as possible for an hour and see how I feel. They went away for about two hours and now have returned.

It’s almost a dull, achey feeling. This is my second pregnancy and I can’t say these are contractions because they don’t really feel that way. I’m not sure what I should do or if it’s something of concern? Anyone ever experience anything similar?
