Omg!!! I can't believe this!

I took two tests yesterday. One of the cheapies off Amazon, and a digital with words and weeks estimator. Both were BFN. Even though I was 4 days late. So I just knew I was out. Took another one today just because I still had some left and it's a clear BFP. 5 days late on my period and on cycle day 37. Even weirder the last time my husband and I did the deed was on October 1st because he had a business trip. So we didn't track or use opk at all this month because I just knew there wasn't a chance! BABY DUST TO ALL LADIES! You're not out until AF shows!
