newly TTC- Is this possible?

Erin
My husband and I just decided to start trying about 2 weeks ago. I've been voraciously reading everything I can about TTC from every reputable source I can find. 
I have been on birth control since I was 15, so about 13 years. I just stopped taking BC about 2 weeks ago. Yesterday afternoon I felt what I believed to be ovulation cramps (quick one sided sharp cramp). I took an OPK this morning and it was positive. We have sex every day usually, so we're just kind of continuing what we usually do there. 
My question is: Is it possible to ovulate SO soon after coming off birth control for SO long? I feel like it would be kind of nuts to get pregnant so quickly, and I'm trying not to get my hopes up because I know it could be a MUCH longer road.
