Questions about Leep Procedure?

So I have quite a few questions. To start off with I am having the leep procedure done at the beginning of October. About a year ago I was told that I had an abnormal pap so from there on out I have been having paps and colpo's frequently. This last time I had a colpo and a biopsy to see how deep the abnormality actually was. First of all the biopsy was about 2 1/2-3 weeks ago and I am starting to have light cramping. Is it normal to have cramping weeks after the biopsy was done? Secondly how hard is it to get pregnant after having the leep done? If one was pregnant before the leep procedure and did not know they were could the actual procedure affect the pregnancy? Any general information about the procedure would be greatly appreciated. I am extremely nervous about the whole ordeal and just need some urance from anyone who has been through it. I know they numb your cervix beforehand but I was told my Dr would give me some sort of conscious sedation before the numbing of the cervix. Was this the case for anyone else? The last question may seem sort of silly in fact I know it is but I can't help but wonder about it. Not only am I having the leep done but at the end of October (just a few weeks after my leep) I am having sinus surgery. Is it a big deal to be having two procedures done so close together? I scheduled them at different times but the Dr.s were available those dates so that's what I went with. It's probably not a big deal but again just curious. Thanks again for any helpful info.
