Am I pregnant ?? 🤷🏽‍♀️

So I’m getting nervous. Period is 4 days late now. I’m experiencing mild 2 seconding cramping for the past 6 days now but no spotting or bleeding. I been really tired, exhausted really and had nauseous feeling yesterday but didn’t throw up. I hate wasting money on pregnancy test, just for it to say negative. (Thought I was about 2 months ago) Should I take the test or wait a little longer to see if my cycle comes on?
