Pregnancy after an abortion

I posted this anonymously because I don’t want to be judged just really want some advice ... nov.3rd I had unprotected sex with my boyfriend we soon broke up afterwards 3 weeks later I found out I was pregnant December 29th I had an abortion due to family issues after my abortion I i bled for 2 weeks we had sex the next week i was told to wait 3 weeks before having sex by a doctor so we did wait our time we were supposed to it was unprotected and he ejaculate in me ... the dr asked me did i want bc during my termination i declined because I’ve been on it before and had bad experiences.. is it possible for me to even get pregnant that early again I know it takes others long to ttc again..
