Nervous...9wks 2days

Brandy
So I go to the Dr Tuesday. I will be 10 weeks. 1st ultrasound. Have one son and it took 18 months to get pregnant again. Have PCOS. I am so scared that there will be bad news. I have been fine until this week and I am just a wreck...it is all I think about and am constantly worried about every little pain. My lower back is killing me right now...is that normal?
