Should I take a pregnancy test

Meagin

Had a brown/pink discharge for about 5 days that happened to stop 5 days ago but now starting to get this type of discharge?? Periods due in about 5-6 days. I started getting lower back pain yesterday night and feeling like I have to take a nap during the day and still go to bed early at night: has anyone else experienced this or do you think it’s period related? Thank you!!!
