Hello dear, I understand your concern. In my opinion the faint line can be due to :- 1)Due to early testing- Usually urine pregnancy test gives accurate results a week after missed period. But in cases of wrong dates or late conception the test can be weakly positive. Here the test need to be repeated after a week. 2)Abnormal pregnancy due to hormonal insufficiency like progesterone insufficiency or any. I suggest you to repeat the test after a week. And also get an ultrasound done to know the status of pregnancy. Nothing to worry. Take folic acid supplements and progesterone insufficiency. Take healthy nutritional diet.Avoid physical strain and intercourse. Take good rest. Hope this helps. Best regards...Dr.Srilatha
