Hate not knowing 😢

Being a FTM really sucks because you really just don't know what to expect. I'll be 39 weeks Friday, and I've been cramping, pooping more (not diarrhea), my stomach gets hard, I've been having lots of headaches, I've had heartburn and acid reflux this whole pregnancy but I feel as if its gotten worse, I just recently got over a cold, baby is moving like crazy today, I have the urge to clean but I just don't want to so I sleep instead. But everyone tells me this is just normal and I'll know when I'm in true labor. I hate that, I hate not knowing when he's gonna come. I wish my water would just break or something so I knew for sure. Ugh. Any advice?
