M.G.
Congratulations!
I just wanted to comment on the cramps that you were experiencing. My fourth pregnancy I had very bad cramping (but w/ small amounts of blood) so I went into the doctor. He told me that it was possible that it was "implantation cramping". That is when the fertilized egg implants itself to the uterine wall and can cause pain and sometime light bleeding. That may have been what you experienced. Be sure to tell your doctor about that no matter what that way he can check you out. Just to play it safe.
I have 5 children and from experience I can tell you that not all pregnancies are the same, even for one mom. I felt like such an idiot w/ my fifth one. I figured that I should know everythin by this point. I read so many books on pregnancy and childbirth and newborns. I probably could have written my own book. But there were still some things that popped up that were new to me.
I wish you all the best of luck. And hope that everything goes beautifully for you.
