Hello,
From your description it seems that you are have had consecutively 3 abortions. Thus, I suggest you to get evaluated for recurrent pregnancy loss before trying for next pregnancy. If possible try to do the following investigations:
1. TSH,
thyroid peroxidase antibody
2. Serum prolactin
3. Antiphospholipid antibody, anti-cardiolipin antibody, lupus anticoagulant
4. Pelvic ultrasound to check for any abnormalities in the uterus.
Try to maintain BMI between 19 to 25,
smoking cessation and limit caffeine intake to less than 200mg / day. You can take
prenatal vitamins daily. Adding metformin can also help as you are having PCOD. You can consider taking
progesterone once you have conceived after consulting your health care provider. You may also need to add heparin and aspirin if your blood tests are not normal. Prenatal vitamins have
folic acid and vitamin D. Hence, you don't have to take them separately.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Praseetha Narayanan, OB & GYN Specialist
