Nice birthday surprise

I have been trying to Conceive since my miscarriage in October. I finally after becoming so frustrated went to my doctor and began testing. Tomorrow is my birthday and the say af is due. My husband bought me a test today for some reason. I wasn't going to take it, I was actually angry at home for buying it because I was bleeding lightly yesturday. To my shock it's positive. This baby had the same exact due date as my 16 month old lol. I am so happy.
