Hi, I am 23 years of age, 5 7 and about 120 lbs. My husband have been TTC for one year now. My last mentrual period was July 3rd 2014, and i have a menstrual cycle typically 27 days. My last period, july 3rd, was 2 days early, and this next period was 3 days late. I was supposed to start my period July 30 and it did not come until the night of the 1st. This shedding has been lighter than usual, but more than spotting and seems to be getting much lighter, which i typically shed for 6 days. Its seeming to only last 3 days, Why is this happening?
