So I am on like CD 65 or something

I went to the DR on Monday and he ordered bloodwork!!! he said I can go back in about a week to see the results!! He said he might put me on something to make AF come, then something to make me ovulate and put me on a sex schedule...LOL!!!!! So lets keep our fingers crossed good things happen in the next month or so!!!!
Question though..........Im thinking he will put me on Clomid or something like that........how much does that increase my chances of mulitples, if any???? DH is slightly freaking out at the thought of twins!!!
