Ok so my symtoms have been weird for a couple of days. My boobs are really sore, I can't even touch them because of it and they have gotten huge! I went up a full bra size. Every time I exhale I get a butterfly/tingling feeling in my chest. I've had constipation, dizziness, fatigue, backache, cramping and restlessness. But I'm only 9dpo. I took atress acouple days ago and came back negative I know if I take another one it will come back negative. Could you be a sign of really early pregnancy or am I just going crazy?
