today, I'm three weeks late. I took two pregnancy tests a week ago and both were negative. I thought I could get blood work done at a clinic but they don't do that in my state. the clinic I called does a urine test followed by an untrasound, or I could go to the doctor and get an order for a blood test, or I could go to the er. if I go to the dr or er, my mom will most likely find out and I don't want a lecture, I'm 19 and live on my own but I don't want to hear it what should I do?
