so normally my period is 4to6 days long and it starts light and gets heavy. I have PCOS so my periods arent always on schedule. However for almost two weeks I have had brown spotting (which I'm not worried about because that is just old blood) and occasionally some red blood that mostly shows up only when I wipe. It is completely out of the ordinary for me. My husband and I have been trying to get pregnant for months now and im already seeing a doctor. i know that implantation bleeding only last a couole days. So I'm not sure what to think about this.
