is this a yeast infection or just like normal cm for someone on birth control? it kinda smells like cream cheese/sour cream but not like bad just the smell is noticeable. it definitely has a yellow tint but you can't really tell from the pictures. it's been happening since before my last period (august 25-september 1) but it's become more sticky and thick. i don't itch or have pain when i pee and my lower abdomen is super bloated. could this be a yeast infection or normal for this part of my cycle?
