Whats wrong with my period?

i used the bathroom and i saw this blood clot so i put on a pad and when i looked in it it was just this lil brown spot but my period felt like it was coming on but it hasn't yet so i took the pad off and now i got a light brown discharge its not sticky or nothing should i be worried but i almost had sex once because they guy broke my wall but that was it and the doctor said im still a virgin because he didn't go in im relieved cus i vowed not to have sex till marriage it was peer pressure but should i be worried he used a condom and it didnt break
