I had moderate endometriosis (caused heavy painful periods)so I had a laparoscopy, hysteroscopy, d
and c,
and another HSG
and the following month and any other time it has been tested, it has been in the 5 to 6 range. So even though the drs wont say one way or the other in my situation I think my endo. was making mine high. I havent researched it or anything but I have no other explaination except that. Maybe something to look into.
