Thanks for your query.
Your ET is quite less.
It could be due to various reasons.
Poor endometrial perfusion is the leading cause.Tuberculosis
and endometrial pathologies should be ruled out.
You can try taking sildanefil or estrogen
tablets after consultation with your doctor.Letoval
is not to be continued after the 8th day.Duphaston
is routinely given as luteal phase support.
For your next cycle, you can switchover to another ovulation inducing agent, provided patency of your tubes has been demonstrated.
All the best
