I had bacterial vaginosis and a yeast infection. Got them both treated. BV didn't go away after a round of antibiotics. Did another round and it didn't go away again. And I haven't been back to do more and it's been awhile. For the past few days I've been having sharp pains in my lower abdomen. I also am having some back pain. Could this be from the BV? I'm on the pill and am due for my period in one week exactly. I sometimes get PMS symptoms a week before but typically sore breasts more so than cramps and if I do get cramps they don't feel like this. Any thoughts?
