I decided to test the day after my period ended. I used the advanced Clearblue OPK. This was the second time I used it. Basically, I wanted to find out if my fertile days were following a pattern: the first time I tested, it was negative 2 days following the day that my period ended. I got the "high fertility" signal on the 3rd day following the day my period ended. I got the "high peak" on the 4th day. This time around, it gave me a high peak the day after my period stopped. Is this even possible? Could the test be wrong?
