BlackAmex,
I'm going in for my third leep this week and it's scheduled two days before my period is to begin. It worries my a little, but I think it will be ok. My first leep was scheduled 4 days before my period was to begin and it actually started a day late. Probably because I was a little stressed out. I had no problems that time and after my period was over I had no more discharge which was nice.
You may want to ask your Doctor since I'm unsure how big of a lesion your having removed - it may help ease any worries about the scab coming dislodged. Just make sure you take it easy. Goodluck!
