Hello! I'm 16 and I've had sex a few times recently. I'm on cycle day 40, which is pretty long. I didn't get a period in December, though I am irregular. I went to the doctors for a check up and they tested my pee like usual. Would something pop up in the test if i were pregnant? Even though it's not a full on pregnancy test. I always use protection, and the doctor didn't say anything about my pee so I'm assuming I'm fine. But I'm always curious.
