I am glad to hear that it is not "fresh". Brown and spotting should still be ok. I am praying that all will be fine.
I know when I lost my babies it was as if someone flipped a switch and all symptoms disappeared. No more sore bb's, everything gone. I think the fact that your bb's are still sore is a good sign!
Have they tested you for sticky blood? Low dose aspirin normally helps to keep the blood flow to baby. This is most likely the reason I lost my baba's. Everything else was fine. Worth a shot!
I completely get you on the "this is the only place" thing. I feel the same as you. Sometimes it just feels like I am going completely nuts.
I am praying for you and we are here for you, good or bad. xoxo
