lol, i hear ya! pregnancy isnt always fun!, the aches, the sickness, discomfort etc... but it is all woth it in the end. hang in there! nearly half way through (woohoo!) rest and take it easy.
a nice warm bath might help with your aches... i ended up having one the other night, sick of lower back pain which was keeping me awake at night, and i found it did the trick.
