    OPK question! I'm confused.
    MrsBurt05 posted:
    Hi there!
    This is cycle 3 of TTC for DH & I, after getting off of 4 years of BCP. I decided to chart and do OPKs for this cycle to increase our chances. With the app on my phone, today is cycle day 15, and ovulation day. Cycle days 12 & 13 I had positive OPKs, cycle day 14 was negative, & today-15, was positive. On cycle day 12 I felt crampy, which I always do around ovulation, and crampy again today. My temperature dropped today after having a steady rise in temperature the past few days. (Sorry, TMI>) My CM for the past 7 days have been watery/creamy & yesterday started the EWCM.

    I'm wondering if today IS ovulation day, and if so, why did my OPK turn up positive? Why did I have 2 days positive, then 1 day negative, then another positive? Is this normal?

    David K Walmer, MD, PhD responded:
    Sounds a little confusing. Let's start from a different perspective. First, are your menstrual cycles between 27-35 days in length (day 1 of flow to day 1 of flow)? If not you may have an ovulation problem. Second, are your cycles regular and predictable, i.e. within /- 1 day of variation? If not you may have an ovulation problem. If the answer to the above two questions is yes, your urine LH surge should be showing up 14 days before the next menstrual period and your cervical mucous should be more watery/elastic the 3-5 days leading up to the LH surge. If the number of days between the LH surge and the next menstrual period is less than 14 days you may have an ovulation problem. Some women with an ovulation disorder have a chronically elevated LH level in their blood and they get intermittent false positives. Another way to see if you are having a true LH surge is to check a serum progesterone about a week before the next menstrual period starts. Another reason that the LH surge could be positive two days in a row is that it is being filtered by the kidney and appears over a longer period of time than it is actually elevated in the urine. I hope that this helps. Good luck!

    Thank you! My cycles are like clockwork. Every 28 days, except this cycle it was 2 days early which caught me completely off guard. I hope just one off cycle doesn't completely screw everything up! I'm still optimistic for this cycle though!
