Does anyone have any experience with this... I usually have very regular periods of around 28 days. My last period was on the 28th of December for 5 days, everything seemed normal maybe slightly lighter than usual but not by much. 15 days later I started bleeding again but it was very light and much darker like old blood at the end of a period, but only lasted for about 3ish days. Does anyone know if it is it possible I could've still ovulated around day 14ish or is it unlikely. Had unprotected sex with partner few times before the second bleed around the time I would've ovulated. I am now 1 day passed the day I would've been due my period but I don't know if I should expect AF now or 28 days from the latest bleeding.. which would make it the 7th of Feb. Anyone got any experience with something like this?
