Did you feel this when you were pregnant?

Well I am 11 weeks today and yesterday afternoon my stomach felt weird kinda like light cramping and stretching. I noticed that this morning my stomach is a little more noticeable. Is this every thing just stretching in their making room. At my last sonogram my dr told me I was going to have a big healthy baby and even moved my due date up cause she is so sure I am going to have this baby early. Well what I am asking is did this ever happen to anyone? Thanks in advance!
