Emma, I had bleeding at 14 & 15dpo with DD. My b/t wasn't until 16dpo and I hadn't POAS, so I was sure it was the start of AF and I almost hit the alcohol stash to drown my sorrows. Very glad I didn't. Also, the FRER lately don't usually get as dark as the control until well after 14dpo.
Miss.B, I had a laparoscopy for endo on Thursday, which involves being catheterised. When they take the catheter out they test that your bladder is functioning correctly. I had to pee and have less than 100ml residual left, but I kept having 200-400 left (after a delay between peeing and the test). Do you know how frustrating it is to pee 450ml (I had to measure all of my output!) and be told there's still 400 left?!?! The last time they tested there was no delay and it was 58ml, so I was allowed to go home! Before that they were talking about having to intermittently catheterise myself at home to drain the residual. *shudder*
