Hey Alana..
congrats on the baby girl!!!
There are many women who use steroids while on birth control.. perhaps if you do a specific search using the keyword birth control you may find the posts..
Also, considering you are on a progesterone based one, you may want to research the compounds in the steroids you are considering and see which ones interact with progesterone to get a better idea of what to use and what to stay away from..
for example, some of found that primo is not good with progesterone bc but anavar is.. etc...
If you find any great research, feel free to post it up here and if it's top notch, I will make it a sticky for other women to benefit from.
keep us posted
