Just FYI, there are other options besides hormonal. No judgement whatsoever, just putting it out there. I know that hormonal methods are often the easiest way.

Has worked for many years for preventing and planning pregnancy.
This is NOT natural family planning method.
Good luck finding something that works well for you!
