Yes.

When I was on the mini pill with Lexie (before DH had his little "procedure", LOL!) I got some small amounts of breakthrough bleeding on occasion, but no AF at all. Drove me mad.

As soon as I stopped taking the mini pill I had a "proper" period.......

(I also had no AF when on the mini-pill with Charlie.......but then I realised I was pg with Lexie....arghhhh!)
