I have been TTC and keeping track of my periods for 3 years now which have been regular ranging from a cycle of 26-32 and no more. I ovulated on September 2nd, husband and I did the deed 3 days before and 2 days after ovulation day. Starting September 11th (9dpo), I noticed very light brown spotting which is still present. I am now 4 days late from my expected period, on cycle day 34, (18dpo) and have light discharge which looks like the egg white discharge with a tinge of pink. Today I recently began to feel strong cramping which makes me feel uncomfortable but is no where near as bad as menstrual cramping. My questions are, What could it mean if I spot for 9 or more days? Is this my period? Should I be worried?
