I have that too. It came on a few days ago. Couldn't wait until monday to be seen, so I went to the weekend clinic. Turns out I for sure have a YEAST infection. oh great....and I had them run tests for other things. If this is only a yeast infection it feels bad. I have pain inside, like where the cervix is, feels like it is sore and burning. And I have clear to milky discharge. You may want to be checked for that. They are going to call and tell me if there is something more. It's driving me nuts. I will take the pill they prescribed and I hope it works. I have always used the creams like Monistat. It has been over 6 years since I have had an infection. So this is new pill thing must have come out since the last time I had one.
Anyhow....I hope you are being seen to see what your pains are coming from. It could be a wide variety of things. Good luck!
