In floods of tears here with my gorgeous 1yo boy here 
I can only be / been about 4 weeks, first month off the pill and not been v well-behaved over Xmas although we're not officially trying.
Have had stomach pain for a few days and thought it was a UTI, hadn't had one before but it seemed like one. Anyway this morning pain was really bad and I felt like I needed a poo badly and also a bit sick - went to loo and passed a single big clot, brown and mucussy, coated in white and followed by more brown mucus. No doubt in my mind what it is. Stared at it for a bit, did a poo
and flushed loo and continued looking after DS. Just called DH as I can't stop crying.
I carried DS with no problems, but it transpired I have a uterine septum, and if the embryo tries to implant into that instead of the uterine wall, it won't stick. Is this the first of many miscarriages this time round?
I'll be under consultant next time due to this issue and have been warned there's a likelihood of repeated miscarriages.
