different schools have different policies regarding reporting OPT status. in my case, the school requires me to report my employment status as soon as any change (like employer, post, etc) occurs and every 6 months, even if there's no change. your school's policy might be different from that of mine. check if there's any information about OPT reporting on your school's (international services office's, to be specific) website. if not, contact them and do as they say. often, school's are pretty flexible about the deadline for the reports, i did mine after about 8 months from my OPT start date and the school was fine with it.

keep on looking for a job. and depending on how good/bad your school is in helping international students, letting them (mainly your IS advisors) know about your situation and asking them for help to find a job might be an option. even better than that, contact all professors, mentors, internship program directors, etc you knew throughout college and ask if they (or someone they know) might be able to hook you up. 

and yeah, some people do spend whole year of their OPT doing nothing, but you don't want to be one of them, neither did they.
