Four weeks of breast pain

I’ve had really bad breast pain for the last four weeks. I’m day 65 of my cycle (30 days late for my period) and have taken both pregnancy and blood tests which have all come back negative. I’ve also been experiencing light headedness, nausea and exhaustion.

I know my blood test came back negative (I got the result today) and it means I’m not pregnant, but I’m still a bit freaked that something is wrong and I am pregnant. My breasts are sore to the point that I’m dying to take some pain killers but I know you’re not meant to take anti inflammatories while pregnant.

Is there any other alternative to soothing breast pain other than pain killers?
