36 days late, having morning sickness through out the day, the past week or so..took a cheap test on day 33, was negative.. what should I do? Have so many signs of being prego, but I have pcos and haven't had a late period in a while. (Years)  And I heard that having pcos can give me a false negative.. I kinda have very mild cramps and feel full down there.. if that makes sense.. been tired,exhausted feeling lately too
