As long as your visa is valid on the day you go, you can (try to) enter the U.S.
There is never a guarantee any time a foreigner goes to the U.S. that they will be allowed entry or how long a duration of stay they will be given. An immigration officer could always, if he feels like, decide to deny entry or give a shorter duration of stay if he feels like the person has been to the U.S. too much recently, or other reasons; but your history of travel to the U.S. seems fairly modest, and there are visitors who go to the U.S. more densely with no problems.
