Talk to Gynecologist on Gynecology

Asalamoalaikum I'm about 8 months married and I had a medical abortion 3 months ago as my husband is not willing to have responsibility of a child at this stage, also the situation of lockdown is affecting us a lot . I didn't have any physical interaction with my partner since medical abortion. Now we both wanted to have it but afraid of getting pregnant again and doing the same act... So I wanted to ask about any proper medicine which I can use to avoid getting pregnant after unsafe interaction.. I also want the proper use of medicine Please help me out
