so abit of a background story, I came of the pill 6/7 months ago now my cycles have been irregular 50 days plus (I’m currently seeking medical help due to this) however my periods have been normal red, medium to heavy flow.

However this month was very different as me and my partner are trying we had sex throughout my fertility window as we got my ovulation day, I was sure we was pregnant. Then just over 2 weeks later my period starts well what I thought was my period. I was on for 11 days and throughout the whole period it was black/Brown.

Is this something to be concerned about I feel asif something is wrong? Has anyone else experienced this or have any knowledge of what it could be?
