Provera and boobs 🤷🏻‍♀️

A

My gyne recommended Provera and Clomid this cycle as I have very irregular periods! I’ve just finished taking 5 days of Provera (3 times per day) and have noticed my boobs are a bigger much more firmer- I’m not complaining but wondering if this is a side effect of Provera?

I have tested every couple of days to make sure I’m not pregnant, but all bfn.
