Symptoms

Just yesterday I've noticed some unusual symptoms. One I will be two weeks past AF due date of 5/20. Two I've noticed I'm more tired than usual. Three I've got mild neausea. And four every time I take my prenatals I throw up. So far every test I took was during the day and it came up negative. So I bought a hpt and I going to take it when I wake up in the morning and see what it says.
