i have been having a LOT of discharge too lately - like you it isn't a thrush (i've had so many of them) or a UTI (had 2 of those!) so i am assuming it is just a normal pregnancy discharge. i am not sure if it is to do with cervix softening or not - i am not very up on these things!
i am not sure when they start doing internal examinations (not looking forward to it). i have a clinic appt on Friday so perhaps i will get one then.
sorry i wasn't much help.
