As long as your abortions were done under the supervision of good doctors, I do not see why you can't become pregnant again. The most common reason abortions used to mess up fertility were because they were illegal and many women went to quacks who messed up their reproductive systems or the women did the abortions themselves using crude methods such as coathangers and sometimes even drain cleaner. This is not to say that abortions nowadays are completely safe. There is always a chance of complications now or down the road but the chances today, with abortion being legal and medical abortions being less invasive than surgical methods, are not that high. You need to talk to your doctor to determine your personal risks.
