Implantation bleeding or Early AF?

Samantha • Mom of a beautiful 2 year old, Emmy. Trying to conceive miracle #2, TTC for a year so far with PCOS.
Last night I had some brown discharge when I wiped. Thought nothing of it as I was hoping it was imp bleeding. Today its been a little heavier but is still brown with a little red here and there. Anyone had bleeding like this and still been pregnant?
