Pid is an inflammation and infection in the fallopian tubes. It can cause scarring and blockages that can lead to an ectopic pregnancy which then causes irrepairable damage to the tube. I had pid once at 18 and then again at 20. When I was 30 I had my period for 8 weeks before they figured out it was an ectopic pregnancy that had ruptured my right fallopian tube. The damage could not be fixed and I nearly died from internal bleeding.

Down the road this means that you only can get pregnant from one side, that would be approximately every other month. The bad news is, they cannot tell which month. You really need a sonogram to check that both of your ovaries are producing eggs since you don't know which side will release. You can increase your odds with clomid and latter ganatatropins(sp?) injections. The older you get, the worse your odds as your ovaries produce fewer and poorer quality eggs as you age.

Hope this helps,
