Hey ladies, I wasn't due af till at least Friday this week but Saturday I had some bright red blood, didn't turn heavy just some when I went for a wee and hardly anything at all on pad. Had a tampon in yesterday for around 4 hours and wasn't even half full but it was brown coloured sorry tmi. My periods always vary from 28-36 days, they usually last around 5 days and quite heavy. I have endometriosis, and PCOS. I started bleeding on cd 27 I did take a test that morning but was bfn with a cheapie. My boobs are still sore and the blood is hardly anything still. I'm guessing my chances are slim but anyone else experienced this before and have your cycles gone all weird I was very confused when I saw the blood Saturday as knew I wasn't due on for a while. Didn't know if this could be implantation bleeding or just an off period. Any advise would be appreciated, month 12 ttc ☹️
