My sister had IVF and I was scheduled to and was a day from starting injections when I found out I was pregnant naturally. (a lot less expensive). IVF is costly and a great option when others have been exhausted. But with the onslaught of fertility treatments and doctors, only about 5 percent of the population that wishes to conceive can't. 95 percent can. Great news overall. One of the things that helps with fertility treatments and pregnancy is reducing stress too.
But once you have IVF, the statistics are the same for miscarriage. One in four pregnancies will result in miscarriage no matter the means of conception.
