Redish brown discharge???

Katja

I just got out of the shower and I had reaaally small ammount of redish brown discharge, it was strechy, didn't smell really like anything but maybe a small hint of blood? My period was supposed to start today but i have had no blood or cramps :(((( I am scared of being pregnant cause last time i had sex the condom came loose but the tip was never in me without condom and he didn't finish
