Ok so usually when AF starts she comes in the middle of the night and I wake up to it all over (sorry TMI) but Thursday morning (6 days late), I caught it as I was getting in the shower. I didn't think anything of it and just put a tampon in. I usually have a medium flow but Thursday I only used 3 tampons all day. Then yesterday I used 2 and by the end of my work day (5:00pm) it was already the old brown blood and the past 2 tampons weren't full. I'm really confused on if this is still considered AF or if I could still be pregnant? Any help would be great.
