Hello all how are you:
If a woman is irregular and takes birth control on a Sunday start (but not knowing when her next period would have came)...when is it safe to have sex and not worry about pregnancy?
I thought that by the time the 3rd week came she should be on the placebo round week and she should be getting her period. Then after the period comes (if period lasts a week), isn't it safe after thatmeaning one month?
Doesn't birth control start a new cycle? She is irregular, so when she starts she doesn't know when her next period should have begun so aren't we making a new cycle?
thank you and I really appreciate your help
