Had unprotected sex 5 times, used the pull out method, now a day late, but also be under a lot of stress. could i be pregnant or just too much stress?

Could be: If your period is late and you have been having unprotected sex (the pull out method is indeed unprotected and not actually a method) you could be pregnant. Do a pregnancy test and if it is negative repeat it in 3-5 days to be sure. Then, if you aren't pregnant, look into starting a reliable method of contraception unless you want a baby now and use condoms to decrease the risk of STDs. Be safe.
