Hi, We are planning for a baby. My last period was on 3rd Dec'21 and had sex on 15th Dec'21. Now I am 6 days late to the next period. So I took a pregnancy test and found 2 lines but one being lighter than the other. Does this mean I am pregnant? I took this twice on 2 consecutive days with the latest at early morning and result was still the same faint line. When should I consult the doctor for this?
