Is it normal to spot on day 18 and 19 of my cycle? 6-7 days after projected ovulation. it was very very little brown in my discharge. can it be stress

Natural spotting: Light mid-cycle spotting of your menstrual cycle can be a normal occurrence. When you ovulate in mid-cycle you have peaks of estrogen hormones followed by lower and changed levels of your reproductive hormones. Progesterone is released at higher levels following ovulation. Sometimes mid-cycle spotting comes from these natural hormonal changes.

Spotting + ovulation: A light brow tinged discharge is frequently associated with implantation when noted 6-7 days post ovulation. Unlikely due to stress. Check a home pregnancy test if your late on your menses, and trying to conceive.
