Before I was ever using birth control, I had symptoms of PCOS... and what worried me most was that I only had periods something like 3-4 times a year (And so was only ovulating 3-4 times a year).
Then I was on birth control for something like 6-7 years... and was worried that when I wanted to get pregnant it would take a long time due to the irregular ovulation... was really nervous about it.
Went primal in June and also got off the birth control in June. In July we also stopped using "other methods" of preventing pregnancy (condoms) and I became pregnant in October.
MUCH faster than I thought it would happen... I can't say for sure it was PB but I feel like if I hadn't made the change in diet and lifestyle, that I probably would've had the same issues with ovulating irregularly that I had had before.
