Hi everyone.
I'm seven weeks pregnant with my first child and today noticed I've been getting an occasional sharp pain under my left ribcage. It's very very similar to the pain of a stitch, and indeed yesterday, when I was out shopping and doing a lot of walking, I kept getting a stitch in the exact same place.
It's not bad (maybe a 3 out of 10) and isn't constant either. I also had some very slight brown spotting yesterday and the day before, but it's stopped now. I'm not getting any pain anywhere else. My nausea has kicked up a notch these past few days which can only be a good thing (albeit unpleasant for me!)
Should I be concerned? This being my first pregnancy (and me being a natural worrier anyway) every little niggle is terror inducing! 
Thanks
