So here's the deal, i had sex 4 days before my period now the whole week i have been mad tired i could sleep til 11am and ready to sleep again at 2 then wake up at 8 and go to sleep and midnight and sleep hard as hell like i worked hard, i have light headaches my nipples have been sore, super sore some nights i wake up a little from even brushing up against them, i had real bad knee pain at one point it went away and white milky discharge no smell, sometimes cramping but not enough pain to take meds, light lower back pain comes and goes, super emotional, always on the verge of ready to cry or crying, and i wipe everyday to check; none of my normal premenstrual symptoms have shown not even bloating and took a pregnancy test yesterday and it was unable to be read, so i just decided to wait to take another one... period 3 days late as of today, any ideas... or completely normal??
