Hi there, I am on the non hormone coil I have my period on the 12th of every month last month was a bit diff after I had my 7 days a week and a week and a half later I started spotting and it was brown discharge and that lasted 5/7 days and now my period is late all up to date with health checks and never had this problem before , what do you think could be the problem ?

p.s I have really sore breasts and now two days late , had a bit of cramping which is normal but nothing like af was coming along . Thanks
