I’m scared to take a test and have it be negative

I have been really really sick all day every day for the past week. I haven’t gotten sick or anything and I’ve been cramping and extremely tired. My boyfriend and I have only just started trying but fingers crossed that we are... baby dust and good thoughts welcome. What do y’all think, should I take a test ?
