32 weeks and having sharp pains

So I'm a first time mum and I've been having super intense sharp pains in what feels like my ovary. I know that this isn't what it is, but it seriously feels like baby is grabbing and yanking my ovary. But the pain is pretty intense. I have my next OB appointment this Tuesday, so I'll obviously ask her about it then. I've had other intense pains over the past few weeks (which actually led to me going to the hospital because it was so bad, but they said everything looked normal and fine). But I was wondering if any of you have experienced this? And if so, did you ever find out what it is?
