Did you take a morning-after pill, or something like methotrexate? If you have retained tissue, you could get scarring that would make it hard to get pregnant later when you want to, but if it's just the morning-after pill, you won't see any tissue. See your doctor and explain what you did and when, so he or she can decide if you need an ultrasound.
im not sure if all the tissue came out. thats why im wondering if would still able to get pregnant. since i didn't come yet to doctor for check up.
Two different things. Taking the 'morning after' pill, which is sometimes called the abortion pill, simply prevents the embryo from implanting in the uterine lining on its trip from the Fallopian tubes to the uterus.
Regarding getting pregnant after having an "incomplete" abortion, well, if the abortion is incomplete, then the person is still pregnant, right? Or do you mean, you had a D&C or D&E and not all the tissue came out, and some of it is still in your uterus?
