S.F.
Run, don't walk to your OB/GYN and tell him/her what's up. There is a surgery to correct. I waited a good 5 years longer than I should have and I kick myself every day for not being more forthright about this. I was so embarrassed to have the same problem as my GRANDMOTHER!!!! My leakage was so bad that I was bringing a change of clothes to work, just in case. I couldn't run, jump, sneeze, or cough without fear of embarrassment.
For me, the surgery to correct was a breeze. It was one night in the hospital and about 8 weeks of recovery. I know that sounds like a lot of time, but two other women I work with did the same surgery and didn't take proper care with their recovery (not overdoing things) and that delayed their recoveries. Most importantly, make sure your surgeon is well-practiced in this surgery.
This surgery was one of the best things I've ever done (other than my kids and getting my tubes tied). I feel like I've been given a new lease on life. Please, talk to your doctor. There is help for this. Don't live with the embarrassment for years like I did.
Good luck.
