Need expertise

So, I've been overly emotional over the whole MIL situation all day, and just now I had some spotting... DH and I were not trying , but weren't exactly careful either. I am on CD 24, I typically have a 31 day cycle and since my chem in august it's been more like a 35 day cycle... Since we weren't trying I have no idea when I O'd... What is the likelihood that this is implantation versus just a VERY short cycle for me (which I have never experienced)?? What do I tell the doc when I see her tonight??

Re: Need expertise

i am no help because i experienced spotting this past cycle (you know my story haha)... but turns out it was just delayed AF. I spotted for like, 4 days before getting it. I do have LP/progesterone issues though. I'd mention to your doc tonight about the spotting, Fingers crossed that its IB!
