See a doctor. Get swabbed for BV and also you may as well do a lost-tampon check at the same time. But it sounds like BV. If your swab comes up positive, the doc will put you on antibiotics, and it's a good idea for your sexual partner(s) to go on the same antibiotic run at the same time to avoid passing it back to you once you're free of it.
I have been having similar issues too.. For many many months now, I have been having a reoccurring issue that has not gone away at all and no one can seem help me resolve it, let alone find the reason for it. I'm at my wits end with this and I'm scared that it might be something more serious. So the last 6 months or more I have been having this horrible horrible foul smelling odor coming from my vagina. and I've done everything I can possibly think of to resolve it. it even smells immediately after I have a shower. it's been so bad that I really feel like my husband doesn't want have sex with me anymore. we went from having sex at least once every 2 to 3 days to virtually nothing.. well like once a month. for me being the age of only 29, that's virtually nothing. I know it's not an STD because I've been with the same man, my husband, for 10 years and I know he hasn't been out with another either. because we're both disabled so we're both home together all the time. but I have done everything from douching, using the summers Eve wipes to clean in between showers and after sex, to using pH balance soap, going to the doctor and being on every different kind of antibiotic and cream that they can give me and everything. nothing seems to be working. I don't have much of a discharge and its normal for the most part. but I do seem to be having stale foul smelling urine along with it. there's no pain and there's no itching. I just don't get it! what is wrong with me? can anybody please help me? I'm so self conscious about it and I'm even a little embarrassed to have sex with my own husband. I feel like the whole world can smell it! it seems to get worse and stronger once I climax after coitus. I just want to get rid of that once and for all. please can somebody help not only give me peace of mind but give me some type of idea what this could be because I'm scared its something serious. due to the fact that I have extreme female problems like PMDD and endometriosis and I've had a hysterectomy because of cervical cancer. on top of all that I also have a tilted uterus and extremely overactive vaginal muscle walls. (which I actually had to go to therapy for) I can't take much more of this if anybody can give me some type of idea of what I'm dealing with or what could be wrong with me and how to take care of it and get rid of it I would be so appreciative and so thankful.. please
Thank you! I'll make an appointment ASAP. It must be BV and not the lost tampon thing because I don't use tampons haha
