3 iui

I had 2 iui in 2020 I got pregnant on the second However it was an ectopic pregnancy I had to avoid for 8 mnts due to the injection then there was COVID so treatment was put on a hold I started a new doc in January tht put me on a diet n I’m currently waiting on my cycle to start before I go to my nxt iui this time with menopur . My first doc had told me it good to do bk to bk cycle as it helps now this will be my last iui I just wanted to knw who used menopur and how good is it?
