Thanks for the responses ladies. It could be the number of babies, I've had back labor also... at least I know it's not just me.
Wow, Rosie! Just 6 weeks, how exciting!! :D
Bimby~ Yay for getting to see your little one again on Tuesday! Time had been going by really fast, but I feel like its starting to slow down slightly now that I've reached the 30s. I still have a lot to do shopping wise so I'm kind of glad lol. May will be here before you know it though. :)
