Been having back pain the last couple days and light cramping with loose stools and nauseous. My baby is measuring two weeks ahead. I'm currently suppose to be 35+3 but she's a bit bigger. She's already dropped and now I'm having more back pain than normal and cramps but only on one side. Like it's wrapping around one side. I don't want to go to l+d for every little thing since she's my first I'm not sure what to expect. And I feel like it lasts so long I can't time it.
