Periods SUCK

I have been so freaking tired these past few days. Glow said my period was supposed to start 5 days from now but I have been having pinkish/brown blood for two of those days. And I have been absolutely exhausted. Usually once I get up and get my day started I wake up and I’m fine but I’ll be at the grocery store and the only thing I’m thinking of is taking a nap once I get home. I get a solid 8-10 hours of sleep. I just have no energy or want to. I just feel blah! Anyone else feel this way before their period?
