Hey everyone,

So I am 2 days late for my period. I usually am right on time for my period or early. Since my cycle has been normal in my adult life, I can only remember being late once. I don't remember how late though. I started spotting. I am not sure if it is implantation bleeding or a sign that my period will start. I took a pregnancy test, and it came out negative. I have had increase in my sense of smell, random nausea, random headaches, back pain, bad gas, some acid reflux, sore breasts, bloating, light cramping, and some spotting. What should I do/think? Could I still be pregnant?
