Am with you on the thrush suffering hun - although I'm not pregnant, I've been suffering with it on and off since Christmas, and it is miserable

Hadnt had it for 10yrs prior to this!! Your symptoms are entirely indicative of thrush hun. It causes the most intense burning and itching I have ever had, and yes the cream does make it burn initially, but when that wears off it does relieve the symptoms.
After trying everything, including oral flucanazole, and canesten I resorted to drinking gallons of water over the weekend (a glass an hour), and it worked! the symptoms subsided over a few hours and left me as quickly as they had come - couldn't believe it. Try cutting down on bread, pasta and sweet stuff hun, drink lots of fresh water and keep applying the cream if you can stand it. I washed every few hours but only on the outside (douching encourages yeast overgrowth), changed my underwear, stuck to cotton pants and kept drinking. So far it has worked for me.
Blood clot sounds nasty, but totally harmless to babies and stitch. It's probably your body's reaction to having the stitch there - it's not 'normal' to have a foreign body like the stitch, and as with a splinter, your body will try to mount a response to it. Take care, and hope atleast knowing what was causing the bleeding has helped.
Please resist poking around down there tho hun, not a good idea at the moment, and might only add to your thrush problems and can spread the infection from the outside in. xxx
