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. 1] Congratulations for thinking of parenthood. 2]As you have irregular cycles it can be due to lack of egg formation or PCOS. This leads to delayed cycles and negative HPT. 3] I will suggest to get USG done to know any structural problem with uterus and ovary, and to rule out PCOS.Husband s semen analysis and Your tubal patency test after menses- HSG- hysterosalpingography, will make the picture clear about the situation. 4] If needed you can take tab FERTYL to help egg formation,follicle study to guide you about day of egg formation, and you can have timed sex activity or IUI on that day. 5]I will suggest indulging in a healthy diet and regular exercise regime. Include plenty of fruits, salads, vegetables in the diet. Have adequate water intake , say 8 – 10 glasses per day. 6] Avoid deep fried foods, bakery products, and refined sugars.Avoid substance abuse, if any. 7] Start on FOLIC ACID, B12 supplements at least 3 months before you plan to have baby. I hope my answer helps you. Thanks. Wish you great health. Dr Purushottam
