if the first time that you had sex was "unprotected" it is always possible to get pregnant. even if you did have a normal period a few days after your sexual debut. yes stress can adversely affect your menses but again so can pregnancy so you should be taking a home pregnancy test or going to see your medical provider to be examined and have a more-sensitive pregnancy blood test.
after having sex for first time first period was normal second is late. is this normal? . okay so i am 22 and had sex for the first time. 9 days later i got my first period on schedule like normal. it's now a month later and my second period is late. i read that stress is a big factor but i am extremely worried. is it normal that my second period is late? is it even possible to be pregnant if my first period was normal? please help.
