I had taken 1st gardarsil jab, 2nd dose will be on may. Can I still try for baby during this duration?

Delay will not hurt. The Gardasil vaccine will still be effective if you wait until after you have delivered. Being off the injection schedule will not affect its effectiveness for this short period of time, and be the safest choice duirng your pregnancy.
Yes --- but. Although there are absolutely no studies showing gardisil to be unsafe during pregnancy, that is the point...There are no studies, period. If you think you are pregnant, skip the gardisil vaccine until after you deliver.
