does this sound like...(poss tmi)

[klee]

sorry if tmi, I am 22 weeks pg and am having sensitivity in the downstairs region when I eat certain things, there is no discharge but I get a hot feeling down there about 20 mins after eating certain things (ie so far narrowed it down to vita weats strange i know). it comes and goes and if i don't eat things like that it doesn't happen, even for whole days at a time. someone mentioned thrush but would thrush come and go like this? oh and it can't be related to dtd because there has been none of that for quite a while. i am off to my gp on friday to see what she says but thought in the meantime I would ask, has anyone else had this or can anyone possibly explain what it could be. thanks in advance for your help, and sorry to be blushing lol
