I need answers

Nicole

I’m new at this... So I’m ttc my boyfriend and I had sex on the January 25th my ovulation day was the 27th and we had sex again Feb. 1st due to our schedule this is all the time we have 😕 so my period isn’t supposed to start until Sunday but I woke up not to long ago to find some brownish discharge I’ve never had this before could this be a sign of early pregnancy? I am nauseous I have a slight headache mild fever back pain the list goes on
