When you are heavier in the later months of pregnancy,you tend to sweat more.And you're more prone to vaginal infections,particularly yeast infections.
When you're pregnant,higher levels of the hormone oestrogen create an inviroment in you're vagina which makes it easier for the fungus yeast to grow to fast.The symptoms include vaginal itching,redness,burning and a creamy,whitish,odourless discharge which can look like cottage cheese.
See you're doctor,who will prescribe an anti-fungal cream or suppository which should clear it up within two or three days.Don't worry,this fungal infection does not affect your baby's growth or development.

You might be pregnant,but it sounds to me that you have a normal yeast infection that all woman experience at some stage in there live's.Do a pregnancy test as soon as you miss your period and if you still are in wonder see your gp and he/she wil check everything out for you.
Good luck on trying and fingers crossed that you are darling,jadexxx
