I'm 16 1/2 weeks, and I have pain in
the morning some days. It has been sharp pain
a few times, but I'm pretty sure it's related to gas and when I'm ready for bowl movement. Sorry for the bluntness, but thought it may ease your mind if you could pin point the pain to something similar.
Probably still worth asking your doctor about... But I wouldn't stress, unless it gets worse or you have bleeding with pain...Then definitely go to the hospital!
