Moving to mini pill from Prostap injections

[Pisi]

Hello everyone! Hope you are all well. Just wondering if anyone could share some experience from using the progesterone only mini pill. I have just had my 7th prostap injection, i am feeling well, no pain at all, and my consultant decided to swap my treatment to mini pill to see how it will go. Just wanted to know how the swap will be, is there any bleeding/period i should expect as she told me i could have some irregular ones or not at all, so if happens i shouldn't be worried. Any bad side effects? Now i am worried about the pain that it could come back as i have been pain free for 7 months. Anything to share with me please? Thank you very much.
