I asked my doctor about the cramping and spotting and she said it is all totally normal. If the spotting gets too heavy (like a normal flow of your period) I would ask your doctor about that. And if the cramping gets really bad or you have really bad stomach pain she advised me to go to the emergency room
Its normal. I was spotting when I was around 7 weeks too and the doctor told me just to rest and take it easy . I am now 28 weeks pregnant
