Boy or girl? Which is it?

So on monday Aaron and I went to Blackfoot for my ultrasound and they spent an hour trying to decide just what sex the baby was. The tech was sure it was a girl and then she'd say "oh wait look at that" so we weren't sure still. She said her guess was a girl. She went to get someone else and when the other tech came in she looked for about 5 sec. and the says"nope, It's definetly a boy." So move over Lincoln you're getting a roomate! Actually I don't know who is getting the roomate. Me and Aaron of course for a little while but we only have one other bedroom upstairs besides ours and Sari is in there. She is a light sleeper. Linclon is all the way down stairs and loves it but Sari and Lincoln wouldn't sleep if they shared a room. Sari is too little to go downstairs. oh the dilemma. I guess I really don't have to worry yet though.
