Possible switch to progestin only pill

[Calypso]

Hi:

I posted last week about going off my pills after my current pack. I am in my placebo week (and got my withdrawal bleed hallelujah - I was worried). I am not currently using any other birth control as i understand i am still protected this week but will start doing so Sunday when I would normally start taking active pills again.

However I am now considering going on progestin only pills when placebo pils are done: the problem I have is with the estrogen.

If I start progestin only pills in place of the usual estrogen pills Sunday am I immediately protected again? Do they also work to prevent ovulation? I know the timing is a lot more sensitive with them.

Hi Calypso,

If you're considering making the switch, the best person to talk to is a healthcare provider. They can help you understand any differences in how the pills work, and explain to you the way to start them if you decide to switch.
