Here goes..I have 28-30 day cycle. Last month I had a twenty nine day cycle with positive OPK on days 16 and 17.. this all fitted nicely with a 12-14 day luteal phase suggesting I O'd, also had a day 21 progesterone test which confirmed ovulation. This month I got a faint line on day 13, a dark line on day 14 and no line on day 15 (using ovunow). Also had some sticky fertile-like CM (although lesser quantity than usual). Since day 17 have felt extremely tired, had an almost constant headache and lots of extra PV discharge (sorry TMI) with a constant feeling of wetness and white or clear in colour. It is not sticky/stringy like fertile CM and is not thrush. Tonight (day 20) I got so puzzled by this loss I did another OPK (thinking not very clearly but wondering whether I'd mucked up ovulation timing) Anyway- immediately got a very strong, dark line- much darker than I have had before. I'd heard you could get a positive OPK if you were pg so I (much to partners "its too early" concerns) did a HPT and it was negative. MY big question now is does this mean that I have not yet O'd or could it be v.early pg with not enough BHcG to detect??? I know that time will tell and I have to wait it out however, I am a lesbian and we are trying to conceive using a known donor. If I had a male partner I would bd tonight to "cover all bases", we have discussed asking the donor for another sample tomorrow night but it is all a bit stressy organizing and doing so and if the strong likeliehood is that I O'd a week ago we wouldn't do another insemination. Just for more info I gave up doing my BBT as I get up anywhere between 4.45am and 7.00am which was making BBT unreliable. Sorry this is so long and thanks for your help in advance, Girldoc
