I was due to start my peroid 7days ago. 4 days after I was due to start I have a brown discharge. It is not a lot like a regular peroid, but I have been wearing a light lampon just in case and there is only 1 spot that has a brown streak. I have felt nauseous, had a headache, sore boobs, moody, but hpt says negative. My mom even asked if I could be. Pregnant since I have so many symptoms. I am just confused by the brown discharge/spotting.

Off periods happen... Sore boobs.. Moody, Headache... and even nausea are typical of PMS , and not uncommon when a period is overdue... even in virgins.

Give it a few days and see if period is just starting up. If no regular period after a few more days, try another test.
