Since the tubes are patent it is a good sign and you do have chances to get pregnant again.Please consult a Gynaecologist and get examined and treated.Also you have not mentioned whether you are having proper ovulation or no and to see that you will have to get done a follicular study
.If the follicular study shows normal ovulation then you will conceive sooner or later.As for the peritubal adhesion
they can be due to infection during abortion
.So try for 3 more months and if you do not conceive the you can go for a laparoscopy
to seperate peritubal adhesion.
