Got my first Bfp today!!!! So nervous feeling right now. Anyway I'm wondering if you guys can help me pin point the date of conception. My period started on the 5th and ended on the 9th. We only dtd 3 times this month, 11th, 15th and 25th. I'm guessing it could only really be the 15th??? As the other 2 would have been too early or too late. The cb test said 2-3 weeks. What do yous think???
