Ok, so Im currently cycle day 33. I was supposed to O on the 9th of Jan but didn't get a positive opk until the 15th. About 6-7 days after that I had cramps, sometimes quite painfull, as if af is on it's way. That started on Saturday just gone but I'm still without af and the cramping is wearing off to a dull lower back ache, which only comes on now and then. I tested last Friday and got a bfn, I'm so confused. Any thoughts?? Has anyone had this same or similar experience?

You ov on 15th (same day as me) so it could be a bit early to test. Implantation can take 6-10 days after the egg is fertilized and that can happen 12-36 hrs after +ov.

As HCG is only produced after implantation I would leave it a few more days and test again as your HCG levels may still be low for the tests.
