Missed ovulation. If you fail to ovulate there the level of norestrogen is low and the tissue breaks down and detaches some. This leads to bleeding. Failure to ovulate will do this. That happens in stress, illness, athletics, and other conditions. The next cycle can be normal.
What causes spotting 2.5 week after period? I'm having red spotting and it just a drop another it pink and brown?
Check out this link. U mentioned pregnancy in ur history. Spotting in pregnancy suggests the possibility of implantation bleeding or potential for miscarriage. Take care and god bless u! http://www. M.Webmd. Com/women/tc/abnormal-vaginal-bleeding-topic-overview.
