I wonder if I had this. I had terrible pain in my groin throughout my pregnancy, which got much worse the final few months. (Walking and sleeping were nightmares!) My midwife told me it was extreme round ligament pain, but now I'm wondering...
I'll tell you the truth- my labor pains were almost entirely focused in my groin area. It was shocking to me, because I expected stomach and/or back pain. But I'd say 90% of the pain was groin. My son was also reversed (sunny side up), but I did not have back labor. Just "groin" labor!
The good news- happy, healthy, perfect son! And I doubt it was MORE painful than anyone else's labor. But I wish I had known that I'd have pain there!
Good luck with your baby girl. Labor will hurt no matter what, so I wouldn't stress about this too much. :) It's rough, but so temporary! And a little girl- lucky you!
PS On a positive note- delivering my baby ended most of my pain! And the twinges I got became less and less frequent, until they were gone completely after a couple of months. Delivery was definitely the cure!
