Trini - firstly - *hugs* :hug: Secondly - yes, it's all normal - trust me if you are UTD you could have already gone into the full hormonal swing of things and you do have a lot to think about if you are. Thirdly - It's good that your DF is excited - at least if you are UTD (which sounds likely) and you have a 'meltdown' you'll have him there, and he'll be feeling strong to support you.
Oh crap i forgot what i was going to write next.
Try not to worry about your parents and your sister too much. The hardest part of Anthony and I finding out i was pregnant was telling our parents - but we had only been together three months and hadn't even met each others parents... Im sure you will find a way, just have your own arguments armed so when they try and shut you down you can argue back at them. And who knows, you might be lucky and your mum might just wet herself laughing and the squeal excitedly like mine did... :lol:
Have your 21st next year... it's no biggie these days really - a 21st doesn't mean anything here in AUS. We already drive, we already drink, smoke, have sex and all the rest of it, it's just an American thing we seemed to have carried on over the years.
All the uni stuff will sort of dissipate once you are actually into the pregnancy, but if it's really important to keep going and get it finished asap - you'll find a way to do so. My mum did her whole first year travelling three hours on p/t each way every day, pregnant and taking my 4yo brother with her. This year should be a breeze. Next year, look into correspondence and i couple of workshops for your pracs or stuff...
:hug: I know im not much use, but babble, rant, vent away.
And :confetti: for the side of you that is secretly excited :dance:
