Hi there,I have understood your concern and I will suggest you the best possible treatment options.
First of all do not panic.
Although your USG is showing thin endometrial lining,it should grow with use of Duphastone and with the effect of
pregnancy hormones.
Retroverted uterus should be checked out by doing per vaginal examination at around 12 weeks of pregnancy. Semi prone position will be of help in such case.
PCOS as such won't have direct harmful effects on pregnancy.
Please fully trust in your treating doctor.
Take
Folic acid and vitamin B 12 supplements regularly.
Opt for a healthy diet and regular exercise regimen.
Include more portions of fruits, vegetables and salads in daily diet.
Meditate regularly.
Think positive.
May God bless you with a bundle of Joy.
I hope this answer helps you.
Thanks.
Dr. Purushottam Neurgaonkar
