Natural family planning method?

Wanted people’s thoughts/experiences with the “natural family planning” method of BC. Like avoiding having sex during ovulation and days leading up. My husband and I aren’t trying to conceive but we also wouldn’t mind if it did happen. Our first time TTC, we got pregnant the first full month. The second time TTC was the third month of trying. Both ended in miscarriage so hopefully this next one (whenever it happens) will be the one that sticks.

EDIT:

I’ve always had a suuuuper regular and predictable cycle. Like, sometimes even down to the hour that AF will arrive. I miscarried at the end of March this year but my April period happened exactly when it should’ve. The exception is that in May AF came 5 days early which was such a shock!
