Period help!!

My period started as normal an everything. I went 7 days which is also normal for me. But everytime I get my period I'm always scared to not wear a tampon days after because I don't wanna bleed all over myself. I have no pads handy now, I'm wondering if I put a tampon in and there was very little brown creamy stuff on it should I keep the tampon in so I won't bleed everywhere?
