Just curious

So I have irregular periods and tend to take oral progesterone after a few months to induce my period. In may we decided that we wanted to start trying with the help of medications. I got a progesterone injection on the 2nd of June and got light bleeding for two days starting the night of the 5th to the 7th. I took letrozole 5mg cd 3-7. Got blood work for progesterone levels on cd 24. Levels read 16. I got a my positive test this past Tuesday the 5th of July. Faint line mid afternoon and digital reads positive two days later even after working a whole shift. My question is it possible I could be further along than 5 weeks tomorrow? Has anyone gotten pregnant with the help of letrozole and ovulated earlier than they thought?
