OP, go to Fertility Friend and read their charting course. Your cycle varies, but it's not that irregular. The key is to figure out when you OVULATE each month, since it seems your ovulation varies by a week or so.

I'd temp and use OPKs and chart online at Fertility Friend. It will take a month or two to get the hang of it, which is annoying, but you will be glad you did in hindsight.

After that, use OPKs every month to nail down ovulation. Have sex then. If you still don't get knocked up, go see a doctor and bring your charts.

Sorry about your BFN, OP.

If you're up for it, I'd start temping this cycle. It helps so much to know when you ovulated and when to expect your period (or to take a HPT). If you've been struggling for several months to get pregnant, the piece of mind of knowing that you've timed things well might really help. Best of luck and I hope this next cycle is the one!

OP Here. AF came today, super late.
