In the present scenario, the best option that is ideal for you is to go for IVF as you have very little ovarian reserve
and it would be a waste of precious time to try natural means of conception. You should see a reputed infertility
specialist and get further management. In view of your advancing age and with a history of previous three caesarean sections, I would never advise you to get pregnant again, but, taking your situation under consideration, you may go ahead for this one more time. Hope this information helps you. Good luck.
