I was supposed to get my period the 5th ended up getting it the 4th and it lasted two days lighter flow but dark and then two days of spotting mostly brown a few times bright redish. My periods are usually 7 days and really heavy! I've never had a weird period ever and I'm 25. I took a hpt this morning and I didn't look closely just didn't see a dark line so I left it and went back to bed. Hours later when I got up it looked weird now I know your not supposed to look at it after 10 minutes but idk what to think!! I've also been having lower right back pain only when I was up cleaning or whatever for two days now the next two days after that it's been a constant pain and annoying!! Someone plz give me some opinions!! Thank you!!
