double period?

so I just finished my period this past week with my regular flow but it didn't even feel like I was on my period, aside from a bit of discomfort with my back (wasn't bad enough to take meds like it normally is) and bleeding I hardly realized I was on my period. now that it's ended however my normal symptoms seem to be present (cravings, excessive hunger, fatigue, etc. ) I'm not sure if this is related to my period at all or if these symptoms are random. any help or comments are appreciated! :)
