Will the gap between F2 and H4 status affect my 485 application?

It is difficult for me to envision that you would have a problem with status given the fact that you submitted your application on time even if H-4 application was not approved for several months thereafter. A copy of the receipt of filing or approval would show the date that your application was received by USCIS, and that should be sufficient evidence to a USCIS officer that you have been maintaining legal status.
