Someone please Help! Am i pregnant????

I am supposed to get my period the 27th but I got it 5 days early so on the 23rd. But also on the 22nd all I had was spotting. My period has been super light. I have no symptom like I normally do which is tender breast, cramps so bad I can't get out of bed, bloating, and lost of appetite. The only thing I have is constipation. I have never been early either. Is there any chance I could be pregnant or is it something else? I have had unprotected sex four times this month and he came in me once.
