Three questions after abortion and one after miscarriage

I had a surgical abortion at 10 weeks in February. Besides the abortion, I have never been to an OB-GYN, but because I am getting married in May, I would like to go soon. Since it is likely that I will move and never go back to this particular OB-GYN, is it necessary that I tell her about my abortion? Will she be able to tell during the examination?...
