I'm 20 weeks pregnant and believe I may have a yeast infection as the opening of my vagina feels very irritated and sore, like I just had rough sex for 3 days straight, which isn't the case for me, its most likely caused from drinking soda's all day everyday rather than water which I know is very bad. So with that being said, what are some safe at home remedies I could try besides loose clothing/cotton undies and cutting out sugar?
