Personally, I would attribute it more to an intestinal thing than anything else, but to cover all the bases I would add some fiber to make sure things are moving along. I would also up your water intake and add cranberry juice - as much in one day as you can handle. If you can't handle the juice, there are tablets available too. If none of these work there is a homeopathic antibiotic for bacterial infections - Olive Leaf extract. If you are sure your bowels are fine and the cranberry just isn't fixing it, take 1 O.L. 3x/day for 10 days. I would also continue the cranberry - very good for that whole tract anyway.

are u alergic to dairy? that can cause it...

You are two weeks past the start of your last period, which would indicate it is ovulation time. Sometimes it can be slightly uncomfortable. There is a long explanation, but you can feel nauseous or have loose bowels during your period and ovulation. So none of this sounds serious to me.

Of course the exercise may be causing tender muscles.

Drink unsweetened cranberry concentrate diluted with water (8 oz. to a gallon of water) to avoid UTI. Plus drink plenty of water to flush your kidneys and urinary tract.

No sweet drinks, they feed an infection. Sugars I mean, any and all kinds.

Go to CVS and tacke some "uristat" and see if it goes away in 2 hours. If so its a uti and should get an antibiotic. But the uristat will hold you over until you do.
