I don't feel anything anymore?

Hello - I'm 39, and 6 weeks today. And I don't "feel" anything anymore? Last weekend I had to nap. And I had cramps most often. Sometimes queasy, but no sickness. Last few days? Nothing. Going about my business, working out, eating right, taking prenatal, drinking water. No spotting or bleeding. I just feel normal. Does this just mean I'm lucky (or I don't know what's around the corner), or could there be something wrong?
