I'm 11 DPO and this afternoon when I wiped after going to the restroom I had very light brown/pink "bleeding". It was more like discharge texture. I've been having cramping, sore breasts and nausea the last few days. AF is not due for 3 more days. I took a test yesterday and it was a BFN. I got a positive OPK on the 13th, so I'm wondering if this is implantation bleeding or AF coming early. What do y'all think? Heres my calendar for reference. Fingers crossed this is our month!
