i am 40, have 2 boys,had a myomectomy 6 months ago, ttc now, started taking fertility blend the day my period ended, my period started January 18th stay for 9 days, first days are light bleeding, then heavy,i ovulated on Jan 31th which is 7 days after period end, i started to have light spotting on Feb 3rd with cramps and terrible breast tenderness,which i don't get during my cycles,the next day light pink the 4th and the 5th. my period is not due till Feb 14th, my question is this implantation or is the fertility blend messing up my cycle?
