Hello everyone!!! I'm here for the first time ))) I'm currently 37 weeks pregnant (in the second trimester) and gave birth in 2020 ?. Question: At 37 weeks of pregnancy, and in the morning I feel like I need to go to the bathroom really badly, but I don't want to. I also feel nauseous, and my lower abdomen hurts like during my period. Is this Braxton Hicks or something else ???
