Whoo-hoo! My lovely CBFM showed me a peak this morning! BD'ed last night, this morning before work, and will again tonight. And probably once more tomorrow night as a final hurrah. Last month, I think I O'ed on Day 20, because I confirmed ovulation through a blood test at 10am on Day 21. So... if history repeats itself (which, in fertility, it's supposed to), I should have ovulated last night or today.
Keeping fingers crossed!
