I'm 16 and sexually active I did have unprotected but also protected for the actually cum I only have had the penis in raw possibly a minute or two until I take it out (tmi) but I always put a condom on except for one time I recently did it in the shower but same thing a little time in the vagina area but I did anal in the shower to prevent the risk of pregnancy could the water have maybe helped the cum slip out ?? I am 4 days late for my period which is rare for me I have only been a maximum of 2 days late and no pregnancy symptoms ?? I only have period like pain in vagina and some back pains
