Okay so I was soposed to get my period 5 days ago, and I had a little spotting. My breasts are sore, and I've had a little cramping, I've been kinda dizzy lately and I get a headache atleast once a day. I took one test 3 days ago and it came up negative. I just don't know what to think. I've also been kinda stressed lately. So I don't know if that's causing me to miss my period or if I'm pregnant.
