Currently cd 65. Cycles are usually 37 days. I seen my fertility Dr and had some blood work done. They said I was about to ovulate on cd 52 got a peak opk that same day now I'm 15 dpo. I has a light spotting once the evening of 13 dpo an since have only seen a small hint of brown once or twice. has anyone experienced it taking longer to ge period after a missed period?
