IN SERIOUS NEED OF HELP 😭😭

Hey guys this is my first pregnancy and unfortunately I have a yeast infection 😔 I called my ob and he said that yeast infection are common in women with pregnancies because of the hormonal change and said I could either but something over the counter or wait till he can see me again which won't be till the 22nd of July 😭 sooo my question for y'all is....if anyone has used this does it work well? I e never had a yeast infection before and I have no idea what medicine is the best to use!! I'd really appreciate it if y'all could help me out ladies thanks 😊
