To test or not to test

Heather
I know everyone will probably respond telling me to test but honestly I don't want to. I'm so tired of seeing BFN for the past year and a half. 
I want to hear from anyone who has had a normal period and still found out they were pregnant. I got my period right on schedule and it ended Saturday but I am so tired recently I can't even keep my eyes open. I also threw up Sunday after eating over medium eggs. 
When I talked with my mom she said she had a normal period and got a BFP a week later so I'm just curious as to how much truth there is to her story. ? Thanks ladies and May the odds forever be in your favor! ?
