They start early, these kids of ours - the torture of being a parent begins at conception!! I feel for you hun, I had easy, complication-free pregnancies but heck no I'm not going to have any more, purely because I hated feeling like you are right now!
It will get a lot easier as your pregnancy progresses, and then it'll get worse as you approach the day you give birth... but, when you're meeting your gorgeous baby, all the morning sickness, the cramps, the worry that something's going wrong, the restrictions on food and activities that you enjoy, and everything else... will all be so worth it. These few months just fly by before you know it (although, while you're doing it, it feels like it's dragging on forever, but once it's over you feel like you were only pregnant for half an hour!), try to relax and enjoy it

Just wanted to offer you some sympathy, I know heaps of women relish every second of their pregnancies but I'm with you - at times it *is* overrated, uncomfortable and downright inconvenient. You're not alone! *hugs*
