Light cramps, no bleeding

I barely remember the first 6 weeks with my son. It's a blur of double quarter pounder meals in a size large from McDonald's because that's all I wanted, then the sudden "I can't eat or I'll throw up yet again but need to eat or I'll throw up yet again", then a positive test at 6 weeks, and then craziness after moving out of an abusive situation.

So I need some reassurance before I freak completely and call a nurse. I've been having slight cramps, no bleeding, nothing majorly painful, the last couple days. I'm guessing I'm about 4 weeks, 2 days along and caught this one super early. I had no positives with my son until 6 weeks and had been assuming I had just ate some bad food or gotten down sick.

Is the light cramps something normal that most of us have had or should I start freaking?

Really hoping to have a sticky baby, going on next week to confirm.
