groin pain?! help!

So my baby boy has been head down most of my pregnancy and when we reached about the 26-29 week range I started feeling some pressure like someone had kicked me in the groin which doctor said was totally normal (pelvic girdle pain). Around 30 weeks I had an ultrasound and saw he flipped into a breech position which relieved the pain for a couple weeks. Around the 34 week mark I started feeling the pain and pressure again down there but it wasn't anything intolerable or super painful and doc had told me he was head down again after physical exam. I'm currently 36+2 today and had my 36 week check yesterday where they did the strep b test and doctor went ahead and checked for dilation. He said I was not dilated or thinned yet (which is normal at this point). However I woke up today and it feels 10 times worse. I can feel the pressure even when I'm sitting still and when I get up and start moving it actually hurts when I move wrong. Is it normal for this to happen or has anyone else experienced this? And what could be causing it to feel worse than it was?
