Hi Maria
Your post seems to indicate that you haven’t experienced bleeding but you have experienced very uncomfortable cramps. Is that right?
It could be that your body is responding to what is to you uncommon stretching for you. Perhaps this is the first time in a while that you are stretching so deeply in this area. I can’t tell by your words whether you had internal damage in your female plumbing back in 1997 but those abrupt changes may mean you had some.
I have no idea whether it’s common because I imagine your circumstances aren’t very usual. Are there particular poses that you can feel this pain? Is it steady and dull, frequent, shooting?
Namaste
Gabrielle
