Yeast infections cannot harm your chances of getting pregnant. There are some people that say if you have the infection for a long period of time without it being treated it can cause problems, but I have had reocurring thrush on and off for 2years (I have had blood tests and things done but they always came back normal) anyway I used to wonder whether that was why I had so much trouble ttc. My doctor assured me this is extremely rare and highly unlikely to cause infertility.
It is very common to get yeast infections while you are pregnant because of increase in hormones and bacteria. I have had it twice during this pregnancy (but this is not unusual for me anyways) It cant do any harm to a unborn baby but should be treated more carefully! best thing to do is to get meds from a doctor. But whatever you do dont take oral meds to get rid of it and be careful with other internal kinds...because of the applicator...obvious dangers!
Because I have suffered so much with it (yes thrush is hell!!) we have been through all the best ways of avoiding it. This includes treating my partner just in case he was the reason I was getting so much, my doctor didnt feel the need to test him for it. He was just given some cream (same kind that is used to help irration in womens external thrush) He had to rub it on the head of his willy 3 times a day for 2 weeks!
wow I didnt mean for this post to end up so long!! Sadly it seems I have become an expert on yeast infections! lol how embarassing!!
