When you got your BFP......

How sure were you that you were pregnant? I've been having so many symptoms the last 2 months. I was absolutely positive I was last month due to the amount of symptoms I had, that was until AF showed up (8 days late). Then this month the symptoms are even more intense. One minute I feel certain I'm pregnant and want to test and the next minute I feel certain I'm not and sure I would get a BFN if I did. I feel like I'm going crazy 😢
