Hi, thanks for using the forum. I will do my best to answer your question with the information that you have provided for me.
Since you have been off birth control for over a year now and are trying to have a baby, I think I would schedule an appointment with the OB/GYN to rule out anything being wrong. This can help put your mind at ease so that you can focus on having that baby. In the meantime you could try an over the counter vaginal lubricant. Good Luck and I hope you get that baby soon!
