Cramping, 6 weeks 4 days

So Work last week killed me, everyday on my feet then coming home to be mummy as well.. but I New the first trimester would be hard with the fatigue! Over the weekend Oliver (my 10 month old) has had a bad cough/cold & last night he was up a lot, in the night I got bad cramping felt like period pains then I fell back to sleep this morning it feels crampy again when I’m moving about or carrying Oliver.. I have the doctors at 10.20 to tell them I’m pregnant so I’ll ask but just can’t remember if I had this the first time round or if it’s because I’m not getting much time to rest?
