i started spotting 2 days before my period for the first time ever. i'm 31 years about 145 lbs and 5' 5" tall. I have no history of any diseases, i did all my std and was cleared. I just started with a new sexual partner about 3mths now but never experienced any form of odor since we've been together til now. i notice there was a very slight change in my vagina jus before my period (same night we had sex...2 days before the period started) but it was barely noticeable, I only noted it because i pay close attention to my normal vaginal odor. now my period is on the 7th day jus sligh discharge but i notice i have a slight poop smelling odor since yesterday when i had more discharge. I put my finger in my vagina and i can smell it even now after a shower. never had this before, what could it be?
