Im 23 years old not on bc and I'm not pregnant so the test said. I had my period two weeks ago. I went to the bathroom today and saw brownish discharge on the paper like I would at the end of my period. I took a pregnancy test just in case and it came back negative. Normally I have 30-35 day cycles. The past couple months have been shorter. Is this normal? I don't have insurance to see a gyno, and the clinics are only open during the week and I work. Should I see a doctor?
