I'm irregular, 32-130 days cycle, I just never know. I've been pregnant 3 times and have 2 kids and I've never needed help getting pregnant. I've never even used OPK's. The last time I did check CM but that's all. The first time I got pregnant almost the minute I went off the pill (MC at 6 weeks), the next it took me about 4 months to conceive and with the 3rd one it was 6 months. All we did was BD a lot hehe
It is annoying as hell though being so irregular, I was sure I was pregnant almost every month and was imagining all sorts of symptoms. I was going insane
