I am going to buy a test here in a minute but my question is ... Ive had white creamy stretchy cm since ovulation last period started march 4th ended march 14th then i had some spotting right after then i had this same cm since then period is 5 days late three days ago i had a negative test on first response im not stressed i gave up trying and decided to just let it happen. Should i test or do you think it will be negative im so sad and emotional for nothing ... Can someone give me hope when their latest positives were.
