@missybear - sounds like what my cycles were doing before they regulated again on the fertility blend. I was getting AF every two weeks. You'll def need to take two a day for the first half of your cycle, then maybe drop to once a day after ovulation has occurred. Hate to say it but I suspect getting af so quickly again means your hormones haven't risen enough and you may not have actually ovulated, despite seeing a pos opk. Or your luteal phase is stuffed due to low progesterone after ovulation. The fertility blend sorts all that out but you'll need more of it in your system than one a day.
My cycles are perfect 28 days on this combo of supps, although I spot for too long after AF for my liking. I'm getting a decent luteal phase and ovulation is occurring, but I'm not having any luck with insemination. Age related of course. Next week will be month 5 with the donor, but he's happy to keep helping me and I'm happy to just go along living my life and still trying.. It's free at least and non invasive!
