Hello,
Surgical is a good choice, many actually prefer it over the medical method (taking abortifactants) because there are generally less complications, the healing time is much quicker, and is over with quicker.
You should not experience any problems conceiving afterwards, and an abortion would have no ill effects on any future conceptions. Many women find that they conceive just as easily after an abortion, and many women have conceived after an abortion and their future children were just fine. In fact there are some women on this board who have had abortions and then went on to have children and their children are perfectly healthy.
Carifairy is much more knowledgeable than I, so hopefully she will answer you quickly.
Sorry I couldn't have been of more help. Wishing you the best.
