Yes, read the Vagisil comment to quickly. I was unaware the company has diagnostic tests on the market.
Vaginal pH above 4.5 usually indicates BV, and sometimes other infection. It also happens during menstruation. Your 4.5 result in on the borderline. But I don't know if the test measures any lower levels. Perhaps it just shows 4.5 or below as a single, normal result. In any case, it suggests your current problem isn't BV.
Thank you, Dr. Your comments were helpful. Just to be clear though, I did not use Vagisil, it's a screening test made by Vagisil that measures the PH level in the vaginal area. A level of 5.0 or higher is supposed to mean you have something more then yeast, such as BV or something worse. When I used the test, it came out as "normal" - a level of 4.5. I'm not sure how accurate this is.
I forgot to comment about PID (the cramping) and yeast (the genital burning). I'm not highly suspicious of either one, but you should ask your provider about them.
One more detail I forgot to mention, I took another antibiotic at some point during the month for another problem, it was Cipro. When I looked Cipro up, it appears it's used sometimes to treat STDs so I am wondering if this should have also cleared up gonnorhea or chlamydia if I had it? Is it possible that Flagyl just gave me a yeast infection? I have noticed that since taking the Flagyl that the cramping has diminished, I mainly now have a discharge & some burning/irritation at the vaginal opening.
Not that it's the main point of your question, but you describe a very typical story for women who suffer from recurrent bacterial vaginosis. As you have learned, some women experience recurrences that are related to having sex, perhaps expecially unprotected sex with ejaculation in the vagina. But despite its association with sex, BV isn't apparently the result of a sexually transmitted organsim. Metronidazole indeed is the drug of choice, but you shouldn't expect Vagisil to make any difference. Research shows it has no effect.
The STD risk from the exposure you describe is very low, although nobody can say it is zero. Since your current symptoms are not typical for BV -- discharge without odor (as you know, odor usually is a prominent symptom of BV) -- you are right to worry about STD despite the low risk and to be tested for common STDs. If you haven't been tested for gonorrhea or chlamydia, that should be done.
But beyond that, I have nothing to suggest. Even though I said an STD is possible, I doubt it explains your symptoms after such a brief exposure. Despite lack of odor, it might just be another somewhat aytpical BV episode. For additional reassurance, though, you could contact your partner and ask if he has symptoms, and perhaps also ask him to join you to be tested.
Bottom line: Continue to follow up with your provider. If you haven't consulted previously with an ObG who specializes in infectious diseases about your recurrent BV as well as the current symptoms.
I hope this helps a little bit. Best wishes-- HHH, MD
Sorry I made a mistake when I typed "The symptoms were still there after I finished the medication... burning, white thick discharge (no noticeable discharge).." I meant to say "no noticeable ODOR"
