Crampage!

I haven't had many bad symptoms until today, well today I started getting cramps. It scared me, even though I heard that cramping is normal. I called the Dr and they told me the same thing, it's normal. They said to stay hydrated and rest during breaks, but I ended up feeling sick, (probably worried myself sick over the cramping) and my boss let me leave. My first semi-bad cramp symptoms... PS - Right now (4 weeks, 4 days) the baby is officially an embryo and is about 2.5 mm long.
