So last month I had my AF On the 6th Thru the 12th, but apparently didn't ovulate until the 29th or around that time I had an ultrasound done and they told me that's when I was ovulating, and then didn't get AF until the 16th of June so CD41. Had AF for 2 days strong, theb stopped mid for a day then came back old blood, took an opk on CD5 of old blood and it was neg but almost pos. Then another through CD6 and it was full blown positive put it into Premom and said i peaked CD6 so BD for those 3 days after AF, could that have been wrong? And took another one today CD10 and it is 100%neg... Should I keep testing opk's or most likely I ovulated already?
