Question about Bacterial Vaginosis:

I have Bacterial vaginosis and have cramping as well - I know that Bacterial vaginosis can cause PID - I am fearful... I did a round of flagyl in Oct/Nov 2009 for the same thing... and then immediately got what felt like a UTI and yeast infection... treated with diflucan & bactrim. I have been successful at treating bladder pain and vaginal flare ups with coconut water and oil since then.  However, I recently had another BV flare up that is not controlled... - May 27th (I did another round of Flagyl) - and Diflucan for the yeast...  my MD had suspected I would and gave me refills of both back in OCt 2009.
 
However, after my period, I now have Bacterial vaginosis again... it was so painful and none of the home remedies gave any relief - probiotics, yogurt, hydrogen peroxide that I had to fill the flagyl AGAIN!  and i started on Sunday - and now already have yeast... it is always at this point that i want to stop the Flagyl...  BUT I have this cramping ...
