Has anyone used the 'calendar method' as a form of birth control?

La

Hey guys,

Just had a baby 4 months ago and want to start trying in the next year or so for another baby. I think it's a waste of money to get an implant if I will just take it out in a year.

We've been using condoms but my husband hates them (obviously 🙄🙄🙄). So I told him we can use the fertility tracking method to avoid pregnancy. My cycle is regular (I've only had 2 period so far since giving birth). I've never done something like this bc I've always been on birth control.

Anyone have success with this? Btw I'm breastfeeding, so my options are limited with birth control.
