Zoladex/prostrap to combined pill query?

[orange3]

I was recently having Zoladex (Prostrap) injections for 4 months whilst on a waiting list for a laparoscopy to remove my endo and potentially an ovary (2nd op).

Due to COVID-19 like everyone everything’s been moved therefore I’ve been advised to stop my Zoladex injections and go back on the pill to try and manage my endo until operations are back up and running.

Has anyone ever experienced going from Zoladex which has suppressed hormones for months to a combined pill which will no doubt be putting hormones back in?

I am only 24 so I wondered if anyone had any advice on managing the large changes to my hormone levels with the switch over and if anyone’s experienced the endo symptoms in changing between the two?

Thank you ☺️
