Well, after yu ask dat question i went researchin for yu :)
I found out that yu could be prego, because some women ovulate while on dere periods so dere is a 50/50 % chance dat yu could be... so yu should get a test!!
And DNT HAVE UNPROTECTED SEX EVER!!!! especialIy on ur period you have more chances of gettin infections!!! I am also 18, yu gotta be smart wen it comes to sex.... I agree wit da ladi above dnt hav an abortion, it can also put yu in risk of havin a child later on in life.... Well good luck wit dat :)
You know you could possibly be pregnant, if your not sure get and EPT. And if you are make sure you be responible for the baby, don't get an abortion, it is something you will regret the rest of your life. I know from experience, there won't be a day go by, that you will be wondering what the baby looked like what color eyes, hair,how tall the baby will be etc. I have for over 30 yrs regretted it and think all the time about all these things I just listed above.
