Week 5 - symptoms

So I have had constant cramping/bloating/backaches for the last few days and it has had me quite concerned. I have been purposefully trying not to look at too many internet sites as they start to make me crazy and paranoid after awhile. I guess what "scares" me is that these are my current symptoms while I don't have any of the more "classic" symptoms such as morning sickness (yet). I keep trying to relax and realize that stressing out helps me in no way. I really hope that our Jellybean is doing well and that my body is just adjusting to being pregnant. Being a first time mom can be so overwhelming!!
