Pregnancy symptom?

Hey guys I’m 26 and I have a regular period usually comes on expected date and everything. Well my period is coming up March 1st and for the last week my boobs have started to hurt to the point where if I touch it gently it hurts. They’re a little more veiny than usual too. I usually get cramps a few days before my period comes but I’ve never had sore boobs. This is a first for me. I’ve had friends tell me it’s a sign of pregnancy but others say they experience that before their period as well
