Congrats on your first u/s!!! Thats so exciting!! I remember the first time I "saw" Hannah, I was 14 weeks along and she actually resembled a human lol!! It was a beautiful experience! And soon you'll hear the heartbeat, and feel your baby move for the first time!!! It's amazing isn't it??
I don't remember if I had cramping that early, but I do know that some cramping and light bleeding is normal. I didn't bleed I know that...mabey some implantation bleeding before but thats it untill I had Hannah..then your body more than makes up for it LOL!!!
