My period...

Is trying to start. I started some light bleeding last night so I put a tampon in and a pad (expecting a heavy flow) and I woke up this morning and it has apparently stopped. Bleh. I am really hoping the Provera works. I am also trying to lose weight and motivate myself to start exercising but it is hard with how smurfed up my knees are.   I cannot even do a squat or anything that includes bending at the knees without being in a massive amount of pain so it sucks. But there are days I am able to push through it. I cannot wait to get insurance so then I can go back to PT for my knees and last time they had to do electrodes on my muscles to get the PT to work.
