I'm late

I have not had my period since last month but I'm getting these small menstrual like cramp, I have been so busy that I have not checked to see if I might be pregnant but I don't feel any different so another reason as to why I have not checked, I have had four miscarriages and I'm scared that if I am expecting that I might miscarry, I also have a thyroid problem. Any positive feedback would be nice thank you.
