sharp pains 34 weeks

A
I keep getting sharp pains right above and (feels like) in my lady area. It last just for a few seconds but OH MY GOSH it's painful. It's been happening the past few days randomly throughout the day. Next appointment is Tuesday. Along with a tight feeling in my lower abdomen sometimes. It feels like I'm trying to stretch a muscle that isn't flexible at all. And it hurts. That last under a min. But I doesn't always happen with sharp pains. I haven't had any tightness lately. Kind of feels like BH but they're painful. Any ideas?
