Well, I was told by my GP that I wouldn't be able to have children after I had the coil fitted. I suffered with Pelvic Inflammatory disease which left me unable to walk for a few days and had to have it removed, and was told that because I had one fitted before I had children, it was likely that there would be damage which would mean no children for me.
DH and I don't use contraception so when, after 4 months together I discovered I was pregnant, we were both in an utter state of shock. We went on to have DD in 2004, but not without our fair share of problems. I was then told that although I had amazingly been able to conceive, I would not be able to give birth naturally, so was advised to think about having a c-section. I had DD naturally, 11 days late.
I fell pregnant again 8 months after DD was born but miscarried at 7 weeks. DH didn't want the baby because of the age of DD and because of the problems we had with her health. I wasn't keen on the idea, but a termination wasn't an option. DH threatened to leave me if I didn't but as it happened, I miscarried naturally.
We decided about 2 years ago to ttc dc2, again no contraception was used and it actually took until Sept 2007. I am now 19 weeks pg with DC2 and am the healthiest I have ever been apparently . I thought the miscarriage in 2004 had played a part in the time it took to conceive DC2 and really thought that we wouldn't have anymore. I had got used to the idea that DD would be an only child, so went to uni and decided to do the things I wanted to do with my life that having DD had postponed. I'm still plodding through my degree throughout this pg.
I was reassured at the EPU when I had the m/c that it would have no effect on future children but in the almost 4 years it has taken to conceive again, I really believed it had ruined my chances. I never wanted a baby so much as I did after that, but over time, I came to accept that it might not happen. Didn't make it any easier though.
Good luck with your book. Pregnancy is such a stressful time, with or without complications and if your work helps other women who have expereinced the same feelings as I, and no doubt countless others have encountered, then that is a fantastic job well done.
