If this is the wrong group, please let me know!

I haven’t had a period since late November/early December, but I had an ultrasound March 17th to determine if pregnancy was a factor (it wasn’t), so my OB put me on 10 days of Provera. Today is day 14 since I took the last pill and no period. I took a test to make sure (FR, attached) and then I took another one bc I didn’t trust that one (cheapie, also attached). My husband and I are over the moon, but I am confused as to how ?? Obviously since my uterus was empty on March 17th, I can only be about 3 weeks right?
