the doctor told me that i have a healthy rigth tube.....
You may not have to do anything but try. But if your tube is damaged then your chances of getting pregnant would depend on how good the remaining tube is. I wonder if your doctor discussed this with you. If your doctor does not know how good the other tube is you can do a Hysterosalpingogram (HSG) to check your tubes. If your tubes are both damaged then you may have to do in vitro fertilization (IVF).
