Spotting, mild cramping and back ache?

Kawehi
Has anyone had this as well. I make 7 weeks tomorrow and trying not to think to much about it. Went to use the restroom again and no blood when I peed. Trying not to think negative, due to in September I had a MC. I am going to the doctor tomorrow and demanding a Ultra Sound tomorrow! Just to make sure everything with our little one is perfectly ok!
