this is my first baby I want I need a little help I'm going to see an OB/GYN tomorrow.

I've been on birth control since I was 14 and I'm going to be 23 has anyone ever been on birth control that long I've had trouble getting pregnant after being on I've been off birth control for three months ? I'm trying to track my ovulation but I've never done it before so hopefully I'm on the right track I just barely got off my period yesterday.
