On 6/9 I checked my cm manually several times throughout the day. Nothing showed up when I wiped after using it. But light tinges of pink was visible on my finger after insertion. That was cd23. My period is due to come on 6/14. No tender breasts but I did feel some cramping mon/tues. trying to see if this may be implantation bleeding/spotting. Or could it be that I scraped myself accidentally trynna check. Or my period is coming. Cycles are somewhat irregular. They range from 25-35 days. Here lately they have been 27-29 days
