Tips or advice to conceive

I have been trying now for about 2.5 yrs with my boyfriend. 1.5 of those years he was out of town for work off and on. I'm very sad because I do not understand why I cannot get pregnant. I have had laparoscopic surgery to ensure my tubes are not blocked and they are not. The doctor never tested to see if I am ovulating though. My next step is to buy and ovulation kit. I am so depressed because when I was 17 I was drugged at a party and woke up to one of my "so called good friends having sex with me" I felt so weird after that didn't talk to him or say anything to anyone. Then I was late I took a pregnancy test it was positive. Told my mom what happened she freaked out and called the police. We gave statement but the guy never went in for questioning so nothing ever happened to him lack of evidence they said. Then my mother pressured me into having an abortion a was only 17 got raped and she said she would throw me out if I didn't do it. I felt trapped I cried all the time but she made me I had no where else to go. I was 7 weeks when got abortion. This has haunted me my entire life. I feel horrible I cry all the time because of it. The only thing I ever want to be in life was a mother. I am 24 now and I feel I did something so bad that I will never be able to get pregnant because of what happened at 17. :( I have been praying a lot. We have since moved and I am looking for another obgyn what test should be done now. His sperm is fine we had it tested. The doctor did tell my that my cervix opening is tiny though which scares me I searched after abortion it can make it tiny does that effect getting pregnant in the future? I feel hopeless and suffer from anxiety and stress mostly because I want my baby and I feel I will never get pregnant :( any ideas suggestions help advise things to ask doctor any medicines that would help etc I'm lost :( thank you
