Lower estrogen after excision surgery

[Pinkruby701]

So, I am 8 weeKS post op from my surgery to have surgical resection of endometriosis. And this surgery was for endo that returned 15 mths POST supracervical hysterectomy. I had severe endo all over again. They removed my cervical stump and all the endo. Prior to surgery my estrogen level was a 70 which some docs say is good for menopause. Some docs don't. My estrogen level had been around 65 to 70 for the entire 15 mths post hysterectomy. Well....now...8 weeks after this last surgery, my estrogen levels plummeted from 70 to 40. And I totally feel it. Does anone know why that would happen?? Were the endo implants supplying my body with extra estrogen??
