CD24 bfn

Well, today is cd24.... I have Pcos and have been on Metformin and Vitex for a few weeks now. Today I had a sharp pain in my left boob for a few minutes, increased white CM, tops of my boobs hurt and I've been so tired mid day that I've actually taken some little cat naps. I didn't track ovulation this month since my RE wants to wait a few more weeks to start clomid again, but I did also have a slight pink tinge of spotting Monday (cd20) morning. Thought maybe implantation? Took a test tonight and BFN *go figure* just a little frustrated even though I know it's still early, it's hard to not get your hopes up 😔
