So even tho i only got the positive OPKs the day b4 on sunday i went on monday and got my bloods done was suppose to be CD21 but obviously as usual it was a sadurday, anyway i got my results back from the monday test today and she told me it was 63, wasnt much help because she had no idea what it was about but my tests back in jan my levels were 65 and he said it was great, so why was i 63 if hadnt even O yet probably? Or does it ruse b4 hand or whats the go, tried googling it but never gave me propper answer about progesterone test 1 day after OPK...
