A little TMI. My doctor said a few years ago that I have endo and May have trouble conceiving. We've been trying on and off for about 4 years now. This month I had egg white cm for the first time since I believe when I was a teenager or started checking for it. We Bd'ed two days before and the day after. Hoping we didnt miss it! At 12dpo I had I would say a "clump" of the white creamy cm with a tiny red dot shown in a previous post. Aunt Flo was supposed to start today but I've been having light brown spotting since 12 dpo with occasional reddish/ pink spotting (so it's been 5 days of spotting now) normally by now I'd have horrible cramps and today would have had a crazy intense Flo and still nothing as of yet. Could I be pregnant and test? Could it be an infection and go see the doc ASAP? Just wait it out and see what happens? I knew this wouldn't be an easy road but I didn't know this would take such an emotional toll on me and how the waiting game just puts my stomach in knots and then when Aunt Flo comes my heart breaks so much more every month. I'm sorry for the long post! I wish you all the best and would appreciate any input from any of you ladies and especially those with endo!
