Okay, let's do a crash course on how that visa works FIRST. :O
It is unlimited entries for the validity of it (6 months from the date it's issued) AND every entry gives you a 60 day stamp. :)
SO
as long as you exit/re-enter the country on or before the expiration date of the VISA (not the current entry stamp you have) which you say is April 9th, you will be stamped in for 60 more days.
