there is a very good chance you could be pregnant, but like everybody has posted before, you can only wait it out & then, if your period is late or doesn't show at all, take a home pregnancy test. if it comes out positive then most likely the result is accurate; if it is false, there is a chance it could be wrong, but it all depends on when you take it. a home pregnancy test is most accurate on the first day of your missed period & any day after that.
as for the abortion, sweetie, that is your decision, not anybody who posts advice online. if you & your boyfriend really wanted to keep the baby, then your parents would come around with time. you would be surprise at how supportive your parents could be, when you least expect it.
i got pregnant at the age of 17. it was my second time ever having sex & the condom broke. somehow, i knew i was pregnant, so when i got a positive pregnancy test about two months later, i wasn't surprised. i was petrified to tell my mother, but when she finally knew, she was really understanding. i won't lie, at first she was angry & said a whole lot of mean things, but giving her some time, she really came around & told me that whatever i wanted to do, she'd be by my side. i opted to have an abortion. it was a hard decision & i didn't handle it so well afterwards, but i healed with time & even to this day i'll still tell anyone who asks that it was the best decision i made at that time. i was just too young to take on such a huge responsibility.
i'm now 21 & pregnant, again. this baby wasn't planned, either, but i am prepared to enter motherhood with confidence. my boyfriend & i considered another abortion, but we both didn't feel it was what we really wanted in our hearts. we couldn't be happier with the choice we made to have this baby, and i wouldn't change a thing.
it's your life, hun, so live it however you want & don't worry what others think or have to say, including your parents. in the meantime, try your hardest not to stress out over this because there is a chance you won't be pregnant & it's not worth getting worked up over until it happens.
good luck & keep us all posted. PM if you need to talk.
