hi, my period was 5 days late, i have come onbut its very light, but my really problem is my boobs, i get very sore boobs for 2 weeks before my period, but because i was late, ive had the pain for 3 weeks and they are still very tender, to the point where i want to cry when i run up or down the stairs, what can i do to stop the pain, paracetamol doesnt work
