I had spotting on 7dpo, and I am currently on 18 DPO 4 days late!!!!..I got a bfn yesterday, and today ive been feeling weird..very hungry but nauseated. Ive heard that you can get a positive OPK when you are preggo! So I took one cus I didnt want to use anymore HPTs and look what I got!! Am I preggo??? I know, im waiting to pee again to use a hpt...whats this mean????
