I'm 35/36 weeks pregnant and have been feeling pretty good on the whole. Since late afternoon yesterday I am occasionally feeling pressure on my pelvis and occasional desparate need to pee (when I don't really). What's bothering me is that my bum really really really hurts. It's like a deep muscular pain. I phoned a midwife who said that as long as there's no bleeding and I can still feel the baby moving I shouldn't worry and should just take a few paracetamol to relieve the pain.
Just wondered if anyone else had experienced anything like this? 
Thanks
