I just asked the same thing today and was told the same thing. I'm 5 weeks and 1 day and Ive been getting cramps with no bleeding
So long as your not bleeding, your fine, it's just your uterus stretching. Congratulations on your pregnancy mama!!
That's exactly how I felt when I first found out.. I cramped a lot like I was about to start my period but obviously I never did lol...I was about five weeks when I found out and I didn't start getting sick and stuff til like 8 weeks
