If its fraternal they may be able to tell but only by ultrasound. Start making a list everytime u think of something that u wanna know. It's easy if u use the memo or notes thing on ur phone. Don't be afraid to ask as many questions as necessary to satisfy u. This is urs n yr baby's life that they r dealing with, they should be used to it.
And be prepared to answer a lot of questions. They will want medical history from both mama and daddy, period history, any past preg, mc, or abortions. Be as honest as possible because they are trying to keep you and baby healthy! Good luck and congrats!!!
