34 or 36?

So tonight I realized a very startling fact... I am 36 weeks instead of 34.  I'm not sure how I was off by 2 weeks this whole time.  In fact, Baby Center sends me an email every week with an update as to how our baby is growing and it reminds me how many weeks we are, they were wrong too.  My sister kept telling me also that I was further along than I thought but I guess I just wanted more time to prepare.    Monday I start a breastfeeding class and Tuesday we start going to a childbirth class.  I know we are pretty last minute with this but I figure a little info is better than none.  The last class is Jan 29 so we probably won't make it to all of them but you never know! Well I'm off to bed!
