Faint positive question
HI... I took a HPT on Wed night around 7:30pm and got a faint but definite 2nd line indicating pregnancy. I thought my eyes were playing tricks on me, but my husband saw the line too. The next morning I used 2nd morning urine different brand of test and got a plus sign that was darker than the night before. Today is Sunday 3 days later and I tested this morning, the positive is still there, yet it isn't any darker. Should I be concerned? I have a doctor's appointment on Friday, but I can go to an Urgent Care center today... I just feel real nervous now.. what would you do????
