Mummakat I know what you mean! I'm thinking of every possible thing that could affect it. I'm finding it hard because I don't know exactly when I ovulate. My temp charts, mucus and blood tests are all over the place so I'm trying to dtd every second day up until about day 32 as I have longer cycles but I have no idea when I ovulated as some of my cycles are shorter. So if I ovulated early im worried I will affect implantation by dtd but I don't want to not do it in case I ovulate later, can't win either way!
