Estrace/estradiol - side effects?

Blooming • 🌈 2 ER, 6 FET 👼🏼👼🏼👼🏼 2 fails, 1 chemical, 1 6w miscarriage, 1 11w MMC, 1 7w miscarriage - getting ready for ER # 3 No earthside baby’s yet

Anyone have any side effects with estrace? I just started it and notice I have been so emotional, I have a headache I can’t shake and some other random things. I can’t seem to find anything online and I would rather hear from someone who has been through this. Are these normal side effects? Should I be concerned? Thank you in advance and lots of baby dust to all!!! 🌟🌟
