Test or no test?

Jess
Hey everyone! I need your opinion. My cycle is typically 36-38 days long. This month, it was 45 days (which is never that long).. i got my period for 5 days but it was EXTREMELY light. I always have regular flows, and one day of heavy. Now that my period is over, i still feel some stomach cramping. Ive felt exhausted for the last 3 weeks or so. And i keep peeing constantly!!! My period just ended thursday. Do you guys think its worth taking a test? Just looking to see if anyone else has experienced this. Thank you in advance ladies!
