Think of taking a test

I had my peiord on 29 of may to 3 of June but round 6th of June i got sick out of the blue. I was throwing up I was off food if I look at food it making me run to the bathroom. The only reason I thinking bout a test was a mate ask my SO if I was pregant as I'm hardly ever sick he was like no and told me what the mate said and now it got my mind thinking. I just don't want to a test if it going to be BFN. We are trying to make a baby
