Q&A: What could cause spotting a few days before my period?
I tend to have brown spotting three to four days prior to my period. It does not happen every month. According to my temp charts and OPK tests, I am ovulating regularly at approx cd13-14 and my cycles are 27 to 28 days. What could the potential reasons be for this spotting? Is it normal or could there be a progesterone problem or luteal phase issue? I was told I don't have the signs for edometriosis. Could it be late implantation spotting, but it wasn't able to implant properly?
It’s probably some lining of your womb that required a certain threshold to maintain, but sloughed before the “rest” of your period when the hormones began to fall … with the rest of the menstrual tissue following like normal. It is possible this could represent a luteal phase defect, but the fact that you’re so cyclic speaks against that. A progesterone test day 21 to 22 can tell you whether you ovulated well. An endometrial biopsy a week later can tell whether the rest of your endometrium (lining) is in sync with the ups and downs of your cyclic hormones.
Endometriosis has nothing to do with this. I don’t believe in implantation bleeding, especially bleeding that’s cyclic.
