Did I miss ovulation?? HELP

Taina
Need a little help. Period fully ended Saturday.  BD on Sunday. I took an ovulation test Monday and It was positive. Took 2 test Tuesday and it was negative but BD anyway. Was my ovulation so quick ?Did I miss my fertile window. Or do I still have a chance. Hoping for a May baby. Also have been taking geritol faithfully since the end if July. Help!
