5 weeks today and cramps in lower abdomen and lower back

Mrs.Toro .

Ok so this is my 4th pregnancy and 3rd child my daughter Milana is 10 about to be 11 my son brandon is 4 and I've had 1 MC and for the life of me I cant remember if I had cramps with my pregnancies. They are mild and go from the front(bottom) of my belly to my back( lower) I know im probably just worried but is anyone else experiencing this at 5 weeks??
