I haven't started yet, but should be later this week. I wanted to do weekly injections, and luckily I didn't even have to tell my doctor, that's what she is prescribing to me. Doing once a month sounds scary to me. Too many hormones at once.....I'm prone to crazy, so no thank you.
Plus just in case I were to have any adverse reactions, it's probably a lot easier to let one week of hormones get out of your system than having to ride out a whole month if it does something really weird.
I'm not scared, you're scared.
