hello. I'm 19 and I always get my period around the last day of the month. The past 2 days I have had a brownish discharge, very light though unlike my usual heavy period. I have randomly been sensitive to certain smells that make me want to vomit, my appetite has changed, my lower back hurts every now and then, my stomach has been a little bigger then normal, sharp pain where I would usually get cramps, but no breast tenderness. I took 2 home pregnancy tests that came out negative. Could I be pregnant?

Pregnancy tests should be taken two weeks after a missed period. Sounds like you took your tests too early.

I agree with TJ, a pregnancy test should be taken 2 weeks after a missed period, using first morning urine. If that test is negative, wait until your next period is due, and if you miss it, test again or see your doctor for a blood test.
