I am a 23 year old female. I want to know if calendar based fertility awareness method is effective?
Yes
Yes, it is effective. You just have to be really good at it!

Hi,
If you have regular periods, then it is a pretty effective form of birth control. Of course, it depends on how badly you do not want to get pregnant. If you absolutely do not want to get pregnant, I would recommend another form of birth control.
I hope that this helps.

Reasonably so , yes.
