Post Plan B

Hi y’all, I had sex (unprotected) 5 weeks ago on December 23rd, the next day I took the Plan B pill, then on January 2nd I got my period but it wasn’t red it was brown until on the 12th. I got my red very very heavy period, I finished one pack of 28 on the heaviest pad that I use every month. My period ended last Tuesday. Everything has been I’ve just been more fatigue maybe and moody a lot more. Today I’ve been having a brown liquid discharge and I googled it, it said it could be a chance of pregnancy but I’m not sure. I have an app with a gynecologist I’m a few weeks. What do you guys think? 😭
