So I started spotting on August 7th (thought it was implantation bleeding since my period is always on time and it was very light). I had sore breasts and lack of appetite. But then Had my actual period on August 11th which was extremely heavy. It slowed down to spotting on the 15th and I am still spotting today. My period is never this long.  Today I had after wiping a big clot like i would during my period. What is going on?
