Okay so it's 1 day before my period and I'm having some signs of pregnancy.
 I have mild cramps. And I only cramp day 2 and 3 of my period.
My back is killing me. My back never hurts during my period.
My boobs are a little sore. Again the only period symptom I get is cramps on day 2 and 3 of my period.
I've been peeing a lot more.
My discharge is all outta wack. Nothing bad. It's just clear some days and milky white and globby on other days.
And I have a little head cold.
I took a test yesterday and it said I was negative. Idk what to do. I did have unprotected sex on 3 of my ovulation days. 
Please no rude comments.. I'm seriously asking for opinions.
