Contractions

I’m 100% sure I’ve been having contractions since 7 this morning. They’ve been irregular but still all day. I called my OB & all they’re telling me is time them and drink water. All I drink is water. Especially since it’s been so hot. I’m scheduled for a C-section 8/19 and I don’t think I’ll make it that far. I cannotttttt it hurts so bad.
