Well I am 12 dpo and we only got the one day to BD and it was 3 days before O. So I know that alone was slim to none chance. Now I am 12 dpo with NO symptoms, in fact all my regular symptoms I get a few days before AF have arrived today. I am due to start Sunday. The one main thing that has me thinking there is just no way, is that temps have not risen at all! Ugh this is getting me so down as I have to spend the entire weekend with my pregnant niece, who is only 18 and here I am at 34 and still no children! SORRY I am just so down today!
