My period has been late for a week and im in fear. i was sexually active with protection. but idk if i am panic- ing alot creating stress.  i checked many things online but im still in fear, i really want to know some more information. idk if im holding my stomach in because im paying attention to it alot or is it really tight. i gain alot of fat during a break because i eat alot of heavy meals and junk food. i do urinate alot after i drink, im not sure was it the same in the past or am i just panic-ing and stressing this out , thinking about this fear 24/7. i also recently just got yellow discharges, idk if it yeast infection or whats the reason? is it stopping my period from coming ? or am i just worrying too much. i'm a teenager
