Concern!!!

Hey guys I’m 18 and I had an abortion 9 months ago and it was a very hard decision to make which me and my SO regret now. I live with my SO and have an amazing job and pay for my own bills. I’m trying to get pregnant but I haven’t gotten pregnant but my cycle is on time but was late in February-April due to stress but it is back on track. I’m going to the gynecologist in a couple of weeks. Is there any advice you guys can give me on any ways to get pregnant and/or any questions I should ask the gynecologist since this is my first time going. My mother said not to tell the gynecologist that I had and abortion since it’s her gynecologist also but I feel like I should to see if that had an impact on me not getting pregnant.
