Hi - My husband and started ttc last July. We sucessfully became pregnant in December. Unfortunately I had a missed miscarriage and had a DNC perfmored at 11 weeks. Since then (and during our previous efforts) I have been using OPKs. I am a 27 day cycle and the predictors indicate that I am ovulating around day 16. This has been consistent month to month, and though this gives me a slightly shorter luteal phase, I have had no reason to doubt the validity of the tests. However, I recently had my progesterone level tested at 7 days after when I "should" be ovuling based on my cycle length and again at 7 days after when my predictor is indicating that I am ovulating. At day 20 I my progesterone was 24.6 and at day 23 it was 10.9. My doctor says that this clearly indicates that I am actually in fact ovulating at day 13 which is exactly where I should be for my cycle lenght.
How is it possible that for almost a year of using predictors, that they consistently show my ovulation as being later. Also, this month I suspect that I had a chemical pregnancy (faint blue line for one day and then all days since, negative results). If that was in fact the case, can that have effected my progesterone results.
Thank you.
Andrea
