Your I-20 expires the day you graduate and therefore you will not be allowed to re-enter U.S. even if you have an unexpired visa. If I were in your shoes, here's what I'd do:
- start looking for jobs from today
- apply for OPT 2.5 to 3 months before the day of graduation
- get hired or at least get a job offer letter
- then go to Germany
Keep in mind: travelling while your OPT application is pending is risky; even more so for you because your visa is about to expire
so the bottomline is, don't leave U.S. for any reason until you get hired or at least until you get an offer letter from your employer
