Your opinon of progesterone simply birth control pills?

I was of late switched to progesterone only from Alesse which be estrogen and progesterone.

I only plan to be on it for a few months until I can attain Mirena (which hopefully will be able to be placed since I haven't have a child- but the doctor says she's have success next to non mothers so fingers crossed!)

So I'm wondering what are your opinions and experiences next to progesterone only pills?

What size breasts?

Too restrictive. You own to take them withing duplicate hour each daytime, there isn't any liberty if you forget and take it a few hours unpaid.
It doesn't always prevent ovulation, or even fertilisation, but it prevents implantation, so no infant that way. Anyone who think that life starts at fertilisation should expect about using a pill which prevents ovulation instead.
