Thanks for the query.
Increased endometrial thickness can be seen conditions like hormonal imbalance and also in pregnancy
So you once go for blood test
If the test comes negative, consult gynecologist once and take tablets to induce withdrawal bleeding.
Then after getting bleeding, track your ovulation and plan unprotected intercourse
around the time of ovulation.
This will increase the possibility of pregnancy.
Start taking folic acid
