Absolutely you can. When I got pregnant with DD (we were trying BTW) I hadn't had a period in over 100 days. I didn't ovulate until around 90 days into my cycle (I tracked my BBT's) then finally got a BFP. The first day of my cycle was in May and I got my BFP in September at 6 weeks pregnant. It all depends on when your body ovulates.
