I did see blood after sex but that was red and this is brown and no didnt use any lubricant. Also it cant be implantation bleeding...right? Because its just the next day and lasted only 2 days and we did use a condom...So i cant be pregnant...right?

Lost virginity on 30th january 2017 evening and had used a condom. Experienced brown discharge on 31st january 2017 around late afternoon. Last period ended on 26th january and have cycle of 28 days.Is this normal?
