Is it possible that you have a urinary tract infection - UTI - (bladder infection)?
You can get these for the stupidest reasons...it's the way our female anatomy is made....if any (bad) bacteria gets in the urethra and it's really easy to do then you can get a UTI.
When you say you feel like you always have to go and sometimes you don't think you'll make it made me wonder if you have a UTI. I've had them to varying degrees...the first one I had I was in my mid teens and drove myself to the ER as I had a fever and wierd sweating and really hurting "down there".
I'm older now (late 30's) and have had a few since then. The latest one was very minor...I only had very few symptoms and waited four or five days to go to the doc. They took a urine sample and sure enough, it was a UTI.
I would suggest you get tested for a UTI. As I said, it's really easy to get one being female with our anatomy....even if you just wipe the wrong way you can get bad bacteria from your anus into your ureathra. They give you antibiotics and if you have a really bad one you can get relief from the first dose.
If it's not a UTI, and you are sexually active please get tested for STD's. The sooner you get diagnosed the sooner you can clear them up with some simple antibiotics.
Let us know how it goes.
oh..and it sounds like you may have a very mild UTI if it's gone on for a month. Like I said...the first one I had I felt like I was DYING
down there. Others thru the years have been less intense....Also, drinking cranberry juice, or taking cranberry supplements is really good for your urniary tract health.....good luck and hopefully keep those orgasms coming!!!
