After what happened last month Id be inclined to go straight to the dr or hospital if the pain is so severe you can't walk. I truly hope you get to the bottom of this and things improve soon. I recall all too well what this feels like sweetie - big hugs to you.

ETA - I just noticed your TTC. Ive been told that if you can have surgery and have a good clean out as it were that it can sometimes assist with TTC> Just a thought. HTH.
