I had a lap in June. I had a normal cycle in July and my first Lupron depot July 19. I had a normal period mid August and a Lupron Depot shot mid August. I had my final Lupron Depot shot September 12 and a short period 3 days on September 15-17. I took the add back therapy July and August. I stopped it mid September. Could I possibly be pregnant. This would be day 37 of this cycle and 42 days since last shot.
