Hello dear Understand your concern Abortion done twice in past does not affect the fertility if done under supervision. But avoid repeated use as it cause damage to endomtrium and chance of ectopic pregnancy in future. Prevention of pregnancy should be done by using contraception. You can choose your contraception by consulting the gynecologist. Your partner can use condoms and you can use Contraceptive pill. Also keep option of I pill. If you will have doubt about contraception, you can take Ipill with in 24-72 hour of sexual intercourse. Hope this may help you Best regards Dr. sagar
