This could be many, many things - not just a std. You should return to your gyn for a full work up. It can be fibroids on your uterus,allergies, endometriosis, a hernia, a bladder issue or even constipation putting pressure on the nerves in that area or many other things. You'll need a full work up to find out what is going on.

That sounds logical to me! I am making an appointment straight away when i get home from work this evening. Thanks for putting my mind at ease.
For the record: I feel just fine right now. We'll see how long it lasts.
