Hi Dr. Purushottam welcomes you to HCM virtual clinic! Thanks for consulting at my virtual clinic. I have carefully gone through your case, and I think I have understood your concern. I will try to address your medical concerns and would suggest you the best of the available treatment options. From your history of irregular periods, it is likely that your ovulation might have been delayed. Usually egg forms on day 13 or 14 of cycle, but in your case it might have formed a bit late and still you managed to conceive. Because of this fact urinary hormone HCG- that causes dark line at T site of the test- might be little less, hence T line may be lighter in colour. Also, I will suggest you stop Tab. Proctinal now. Please get USG done to know viability and gestational age of the baby. I hope my answer helps you. Thanks.
