Your symptoms are a very normal part of a healthy pregnancy. If you are having trouble keeping food down, don't stress too much. The baby needs very little right now. I am 12 1/2 weeks and just have the very slightest "bump"...mainly I just feel fat (LOL) but otherwise I feel great. You will get through this in a few weeks and soon you will be enjoying your little "bun in the oven". Well wishes!
Feeling sick may just be a part of the joy we pregnancy. As long as you're not seeing weird discharge, severe cramping, or bleeding (not spotting) then you may be fine. But if you really want to know what's going on call to schedule an ultrasound and voice your concerns. I hope everything goes well for you. :-)
