Estradiol (delestrogen) injections

Hi! I’m wondering what everyone’s experience has been with estradiol (delestrogen) injections after a positive beta. Prior to my frozen embryo transfer I was on estradiol and then progesterone injections and I’ve been told to continue both now that I’m pregnant until about the 10 week mark. I’ve heard about a lot of you continuing progesterone for 8-10 weeks but what about estradiol? Thanks in advance!
