I had a '74 in the UK and the worst thing I did was to sell it b4 we left. The new well old one really is a '70 so she is 41 exactly like me, lol.
Do you know yours and your hubbies blood groups? If you are O and your hubby is A or B, O is very naughty and rejects As and Bs. You can help with this by following the ER4YT diet and I know there is something your natropath can give you to help your uterus be less hostile. I know someone in this situation, who has also done IVF. She half heartedly followed ER4YT after stopping IVF and fell preggers, sadly it didn't stick but it stayed with her a lot longer than any of her other natural or assissted pregnancies. She is now follows ER4YT 6 days a week and has lost 15 kilos, she has also taken a supplement from natro which has made her uterus less hostile. She is now really positive about TTC as well as the fact she feels a whole lot better in her general health. Anything is worth a try, fingers crossed. Mwah
