Recently, I’ve been noticing a strange odor coming from my vagina. There is no itching, burning, redness, pain, swelling, or any other abnormalities. The odor is reminiscent of the smell of leaving a tampon in for a little too long. I’m on birth control and accidentally missed two days when I lost my pill pack last week, and started spotting.. this is when I noticed the odor. This was probably last Thursday (4-19). I had just ended my period the Saturday before. I’ve been taking my pill consistently since Thursday and it’s still not going away. The only time it subsides is when I become aroused.. in other words, my “cum” smells normal..
