Oh, I'm so glad that this thread is active! I was wondering the same thing myself. We just found out this week that we're pregnant with our first!
But for the last 3 weeks I've felt bloated ( I seriously feel like I"ve already gained 5lbs!) and super crampy, it didn't bother me at first, just thinking my cycle was funky this month, but once I found out I was expecting I started to worry! But it's all normal?
