My periods are, and always have been super regular. They used to be super heavy and painful until I went on the pill at 17 to help. I can’t really remember when they changed to how they are now but for as long as I have been ttc and therefore laying more attention, I’ve noticed they seem weird. They’re still very regular. I will have brown spotting the night before af is due. I will then have about 8-10 hours max of red bleeding (medium flow, I’ll use about 3 tampons although won’t fill them) and then for the rest of the day and for about 2-3 maybe 4 days later, all I’ll have is brown bleeding or brown spotting. I know brown blood is old blood but is it normal to have such little red flow and so much brown?
