Letrozole and gonal-f injections

Alisha
My husband and I have been TTC for 3 years. We recently completed a lerozole and gonal-f injection (combination cycle). I'm currently in the 2WW. I ovulated a week ago. I probably got ahead of myself but I took a pregnancy test today which came back positive (very light 2nd line). Could I be pregnant or is it just the meds?
