Its almost an year since last pregnancy. Get your hormonal profile done again. If TSH and prolactin
levels are abnormal then it needs correction. You need to undergo HSG or SSG to confirm patency of tubes. Genital tuberculosis
to be ruled out. If these tests are already done and are within normal limits, then you should not worry. Try to make contact at the time of ovulation using ovulation detection
kits. continue folic acid
tablets. If you don't conceive in 6 months, you may require ovulation induction
medicines to produce more than 1 egg in your ovary to increase your chances of conception.
All the best
