Look on your certificate (digital copy here). It shows the "certification cycle" in the bottom right corner. These are the dates during which the CPEs need to be earned.
Regarding double-credit, please see page 10 of the CPE Handbook. I believe the same rule applies, regardless of the "type" of CPE.
And, since you "passed the exam" yesterday, your next step is to complete the endorsement and pay the AMF. After that you become certified and are a "member". Normally, it takes about a month for all of this to complete and then your cycle starts on the first day of the following month.
