Hello Thanks for writing to us with your health concern. You have been trying to conceive after having had a prior conception. THis is called secondary sterility. You need to consult an Infertility specialist in your area. First the routine blood work should be done - COmplete blood count, viral markers, blood grouping, FSH, LH, TSH, Prolactin, OGTT etc. ALso your husband s semen analysis should be done. A follicular monitoring should be done to check the growth of the egg follicle. IF that is not adequate, then ovulation inducing agents maybe given to bring about ovulation. Also a hysterolaparoscopy is in order to learn whether the uterine endometrium has been damaged or the tubes have been blocked. In addition to this is the factor of your having had recurrent miscarriages, which complicates the picture. PLease consult a high risk pregnancy expert. Have genetic testing for yourself and your partner. Also screening for antiphospholipid antibody syndrome. I hope chromosomal analysis was done for all the prior pregnancy losses, it is an important step. A hysterolaparoscopy would rule out any uterine abnormalities. Take regular 5 mg per day folic acid supplements. Maintain an ideal BMI. Take care.
