Contraception

Assalamu alaikum, With lots of hope I have come to your page please ask Babar bahi to answer my this question. I have been involved in a physics relationship before marriage for that purpose I used to take contraception pills. I have repented from this sin but suddenly I have realized I took that pills to avoid pregnancy which is equal to taking a life. I have consulted with a lot of scholars but they said taking life is when you aborted a soul after 4 months of pregnancy. But nothing is comforting my heart I feel like only way to calm my heart is to go to jail. Please help I can't eat drink sit & sleep. Please help what should I do please help.
