I had a molar pregnancy of last april. Can that be a reason I can't get pragnent now been trying every since?

Molar pregnancy. Usually after a molar pregnancy it is not wise to get pregnant right away. There is a recurrence risk. If you can't get pregnant a year after a molar pregnancy, you should see a reproductive endocrinologist for help.
No . There should be no connection between molar surgery and the ability to conceive.
