I am 15 years old, I am not on birth control. i have protected sex with my boyfriend but we have done it un-protected for a matter of seconds. Last month i had my period on the 14th of april and now its the 18th of may and i havent had my period yet . I dont feel any symptoms and maybe its a stupid question, but should i take a pregnancy test? How many days after my missed period should i take one? Would i for sure notice symptoms if i was pregnant?
You can take a pregnancy two weeks (preferably three) after you had sex.
Your period isn't very late yet, and you're only 15, so it could just be due to random abnormalities. However, since you had unprotected sex (even if it was just a few seconds) there is a slight chance of pregnancy, so I would suggest taking a test. No, you would not notice any symptoms necessarily- the only way you'll know if you're pregnant is if you take a test.
