I m just trying to figure out why my period was late when it s never late ,it start the day it was supposed to end which is 4 days late and the blood was very light and a couple drops and the next day small clots but heavier bleeding. lately I ve been feeling nauseous, tired,sick, and have veins in my breast and do feel some growth,I took a pregnancy test and it was negative . My husband and I have been trying to concieve and keep track of everything we did do it several days before ovulation and the day after .
