I had a MMC with twins back in March and we've been trying again I had a positive OPK on July 28th but my LMP was on July 12th. that last pregnancy I got a positive test 4 days before my period was due. They were twins too but I know others that had positives before their LMP I haven't heard too many stories of negatives and then a positive too far past missed period. I'm usually right on tho even if I ovulate later I'm usually 29/29 days tomorrow will be day 30 for me Sunday 31. Should I wait for AF to show or take a test again?
