hi i am 17 and my boyfriend and i have had VERY protected sex ever since around mid/end of march 2017. It is now april. My period was supposed to come april 13th. Im nearing 8 days late. He NEVER ejaculated in me. EVER. We have been very careful of that. Am I pregnant? Any guess when my period should come if it will at all? What is wrong? Ive showed zero signs of anything.
