4 days post IUI

We are four days post IUI and today I have had some slight cramping; mostly on the left side but sometimes on the bottom right side. Who knows, it is probably nothing and I am reading too much into it but I am trying to listen to the nurse. She said that today would be considered day 3 and that means if there is an egg these would be the next three days that they or it could implant. So I have been careful and been asking the hubby to lift things for me and I have been as calm as I can be. So that is it, not much for today. TTYL!
