I was ttc for about 2 and a half years, hopeful at first, which descended into depression and despair after about a year and a half. I saw people come and go, falling within a few months, having easy successful pregnancies, completely oblivious to how unfair it all was.
I had two chemical pregnancies. TTC changed me as a person. I am still bitter, despite currently being pregnant from our first round of IVF. I am annoyed that I had to go through all of this when for others, it's as simple as a click of the fingers. I am having a difficult pregnancy - nothing dangerous, just numerous small complaints (anaemia, severe pgp and some rib flare).
I saw hope peddled too often when there was none. I am a realist, not an optimist. I suffered depression and had to leave my profession as I couldn't cope with the stress of that and the stress of ttc for so long in that endless cycle of hope and despair.
So I researched. I am a scientist anyway (not a biologist by training). Knowing facts, figures and statistics helps me to temper my expectations.
I suppose I am just still very resentful of what a difficult experience I had when so many women will just have sex and fall pregnant and be none the wiser to the difficulties that so many other women confront when ttc. I wish my experience had been as blasee. I am sorry if I have taken any of that resentment out on you.
Honestly, it's great that the dream coincided with your being pregnant, but there is no scientific evidence to back up this being more than simply a coincidence.
