Hello! I am in need of some information to ensure that I am not crazy :)
I am 30 yo, mother of 3. Currently 5 dpo and experiencing nausea, vaginal dicharge/mild itching, faint "rose colored" spotting after using the restroom. With my preceding pregnancies I had what I thought to be a yeast infection prior to when I was to get my period. It has been 10 years since I had my last one, so I have forgotten more than I have remembered. Are these possible indication that I have conceived?

It would be too early as implantation would not be complete at this stage. Maybe you ovulated sooner than you thought. Regardless, it should be checked to determine if an infection is the cause.
