cramping at 9 weeks

I am 9 weeks pregnant after 3 mc in the last year (all happened before 6 weeks). I have 2 healthy children ages 9 and 11. I have cramping throughout the day for a couple of weeks, the dr says its normal if there is no bleeding or spotting.  I dont think I had cramping in my past pregnancys.  I saw the babys heartbeat 2 weeks ago in an ultrasound so I hope all is good.   Some friends have told me that they had bad cramping the whole first trimester.

I had cramping throughout my pregnancy due to the uterus expanding.  I wouldn't worry about it.  Have a happy 40 weeks.
