Ranting.

"I was on my period."

"My cycle is super long."

"He didn't finish yet but the condom slipped"

"I took birth control pills after."

They always end with "Can I be pregnant?" Let me make this clear for those of you who don't get how sex works: if the penis enters your vagina, YOU CAN GET PREGNANT! That's the main purpose of the act of sex! If you don't want to get pregnant, avoid sex! Protection, no protection. You have sex, you take the chance. If you think you could be pregnant, wait it out, take the damn test. There's no other way to know if you're pregnant or not other than taking the stupid test.
