Why??!!

I don't understand why people ask if they can be pregnant w/o taking a test. Just take a test stop asking if you could be pregnant if your having this symptom or that symptom. Just a rant I had to do. It is getting annoying seeing these questions. Every other post is asking does this mean I can be pregnant or my head hurts am I pregnant or I'm nauseous am I pregnant. Come on I know we all have more common sense.
