Hi Michelle
Congratulations and here's to a happy and healthy pregnancy!
Think yourself as lucky hun. I am 18 weeks pregnant now and like you my only main symptoms at your stage were stomach cramps (still, that was bad enough!), sore boobies and tiredness. But I know some women go through hell and high water, so we have been lucky ;o)
I was so worried too before the scan, especially as I found out I was pregnant at 4 weeks, so had to wait ages for the first scan and it was horrible having to wait all that time. But honestly, I am sure you'll be absolutely fine. Just wait until you see your baby for the first time - amazing stuff!
Who knows what's to come but what I've learnt already is to take each day as it comes as there are so many things happening to your body and it can change daily, just try your best to relax and enjoy the experience.
All the best to you Michelle, hope all goes well.xx
