Early in pregnancy, the time of day you take it matters in getting an accurate result because the hormones are low still. also a faint line is still a line.
Maybe faulty test. You can get a false negative. Take another one or go to Dr?
I would suggest calling your dr and scheduling a blood test. You could just have low hcg levels.
You might jus be to early. That happen to me
How scary. Maybe grab another good quality test and wait until tomorrow morning to get a concentrated urine result.
Go to your doctor or local health clinic.
Health clinic will most likely just do another urine test. Doctor can do blood work to tell.
