Flu symptoms and light brown discharge 7dpo

So the day I got my positive Opk and around when I should have ovulated I felt fever,chills and muscle aches and fever of 99.6 which I'm normally 97.6 It lasted less than 24 hours. I felt totally fine after that. Exactly a week later (today) I feel the same way but have a 100 degree fever and I had a very light faint brown discharge when I wiped. I'm 7dpo...last time I was pregnant I thought I had the flu during the tww. I got a BFP a week or so later, then had my daughter. She was our first and we lost her at only 3 days old due to a heart defect. After she was born and my milk came in I had the exact same flu feeling. Can this be due to hormones? My husband thinks I could be pregnant but the faint brown is making me think I'm Prob not. We both want it so bad since our arms are so empty.
