Since you had one pregnancy
naturally then you should get pregnant as there should be no major problem.But since ironically you had to get aborted.If you have regular periods;ovulation is proper;semen analysis
of husband is normal and fallopian tubes are patent then you will get pregnant as these are the main criteria to get pregnant.So get examined by a Gynaecologist and if required investigated to see the patency of tubes and go ahead and you should get pregnant sooner or later.
All the best.
