Still waiting...but

I am still in the holding pattern, its too early for any of my symptoms (huge, sore breasts, crampy uterus, tired, nausea, etc) to mean anything. I truly believe all of my symptoms are related to the PIO I take nightly. I have felt calm and cool...up until today. Not sure why, but a fear of failure hit me, a fear that I will be crushed and I will never get pregnant. I am trying to be positive and upbeat, and for the most part I am managing well. Today though I am scared of never having our dream of a baby fulfilled. I am a little more irritable today, I am cramping more and it seems to be concentrated on my right side, the same place that hurts every month before I start my period, or right before I ovulate. I never had this pain until after the cornual pregnancy. I had a HSG to make sure there were no blockages in my tubes or malformations in my uterus. The RE showed us the video of the HSG and we could plainly see that my uterus looked great and both my tubes were open and clear. I had the trail transfer right before we started the stims and my uterus checked out ok. He has never mentioned seeing any scar tissue and I have had more ultra-sounds than I can count. So why do I have pain in this one side every month, and why is my cramping primarily on this same side? I am so afraid I am going to have a repeat cornual/ectopic pregnancy. I know embryos latch on to scar tissue, what if I have scar tissue at the entrance to my uterus from the tubes. Maybe I am reading , researching and analyzing everything too much. They say that sometimes a little knowledge can be dangerous, maybe it is dangerous for my brain to have access to all this info, it makes me worry more instead of reassuring me. Also my DD's teacher, who is pregnant, she told me about her friend that did IVF, transferred 3 eggs and ended up with an ectopic pregnancy. I know she meant know harm, she was just sharing an infertility experience with me since her round belly was obvious proof that she has not been experiencing infertility. It still put an ugly picture in my head though. I don't want to worry, I want to be filled with peace and calm and positive thoughts so that I can send warm welcoming feelings to my embryos, so they will be more likely to stay. I talk to them everyday, telling them to find a nice warm spot and to snuggle up for the long haul. Not sure if it is working, but it can't hurt....right?
