Still doesn't feel real...

So we're a little over 9 weeks now with our twins.....hubby seems to be past the shock factor but it still doesn't seem real to me. I've seen them twice on the ultra sound machine and my stomach is definitely growing (although I know it's only bloat right now) but I still feel like anything but could happen and o don't want to get my hopes up. Then yesterday I made the mistake of looking into maternity leave - I'm a teacher- and freaked myself out. We only get 60 days unpaid leave with benefits then after that we can take more time but it's the principals decision to hire you back or not and your benefits become your responsibility. With having twins I could be delivering at any time and being s planner I did the math from 37 weeks and it takes me to the last month with 5 weeks left. If I do go back I feel it is way to early to send them to daycare but we don't have any family down here. So now on top of still being in la la land about being pregnant I'm freaking out about maternity leave - ugh! Sorry for the rambling - just needed to get this off my chest.
