I'm a ftm and I'm freaking out a little bit. I'm 31 weeks along and I'm having pain that starts in my back and radiates to my front. It's quiet painful and it's happening just about an hour apart. It started around 2 this afternoon and it hasn't stopped. I feel like absolute crap the pains making me nauseous. I don't think I've lost my mucus plug yet and I haven't noticed any unusual discharge. I'm not sure if I should give my ob a call.. I don't want to seem like I'm overreacting. So someone please tell me this is normal!
