Hello there.
I'm glad that this theme exists (although I am not glad women experience this).
So, I am spotting each month, starting from 6dpo or 7dpo, until my AF comes.
Did all blood tests, all came good (progesterone 21th day is 18), regularly ovulate on cd 12. I have a luteal phase of 15 days.
My spotting looks like brown discharge, sometimes only as (TMI warning) a chocolate brown flake on underwear or pad, sometimes as really dark, almost black tissue.
The first time when I get it in a month (6dpo or 7dpo) it looks like breakthrough bleeding, I see a solid reddish watery discharge on toilet paper when i wipe after using the toilet.
I am trying to conceive no. 1, for 4 months, and I am 30 years old.
I bought online natural progesterone cream, should I give it a go next month, if my AF cames this month (12 dpo currently, AF due in 4 days, spotting from 6 dpo)? Although my blood tests are OK.
I regulary chart, use OPK and follow everything concerning my female health ever since I ttc.
I do not know if anybody is active on this theme, but I will keep it updated in maters of my own case!
Maybe it will help somebody who is dealing with this too.
