I am a 30 year-old female and my fiance and I are trying to conceive. Just last september 17 I had my period and it lasted for 5 days. A week after that, I had a brown discharge that went on for a week. I am on a 28 days cycle and I still don't have my period and today is 21st of October! I took a pregnancy test last night and it's negative.
What could it be? Am I pregnant or just delayed? please help!
