I got a BFP this morning!?

So, my period was five days late which is very odd for me because I'm ALWAYS on time but it was late this month. I took a HPT this morning and it was very clear...a positive! I've been trying for six months and was giving up hope and the past two months, my partner and I stop "trying" and just went with the flow. I'm going to call my doc tomorrow and set up an appointment to have it confirmed!
