My 14 year old baby sister and I might be pregnant at the same time....

My sister feels way more comfortable talking to me about this stuff than she does with my mom. So when she lost her virginity a few months ago, she came to me. Now, she told me she had sex again last month, a week after her period had ended (which would have put her mid cycle, so she actually could have been ovulating). She thinks she might be pregnant. My fiancé and I are TTC, and I'm currently in the 2 week wait (11 dpo). Basically, she could be 6 weeks pregnant and I could be 4 weeks. *nervous laughter*
