I am 36 years old trying for a baby since 6 month. I have 1 kid six years old before him I had two missed miscarriage 6-8 weeks miscarriage as foetus heart beat not visible/ came. I would like to understand as I conceived easily before but now when I am trying since six month on regular basis I am unable to conceive my reports are normal have a medical history of thyroid. I am not obese. My periods are regular 6 days /25 days cycle. Smear test is also normal. I am also taking pregnacare tablets as prescribed by doctor since 6 month. I would mention that my previous pregnancy was high risk pregnancy I conceived naturally but I remember doctor prescribed me with susten injections twice in a week and susten capsules as well. Sometimes I feel that everything is fine but implantation is not happening one day light spot then bleeding stops and then after a day period starts it's so confusing what is happening. Please suggest why this is happening is it normal or I need some treatments?
