Dear Haleymummy, sorry about your loss..
Below information is what I had retrieve from a website : -
The reason for miscarriage is varied, and most often the cause cannot be identified. During the first trimester, the most common cause of miscarriage is chromosomal abnormality – meaning that something is not correct with the baby’s chromosomes. Most chromosomal abnormalities are the cause of a damaged egg or sperm cell, or are due to a problem at the time that the zygote went through the division process.
Other causes for miscarriage include (but are not limited to):
- Hormonal problems, infections or maternal health problems
- Lifestyle (i.e. smoking, drug use, malnutrition, excessive caffeine and exposure to radiation or toxic substances)
- Implantation of the egg into the uterine lining does not occur properly
- Maternal age
- Maternal trauma
Factors that are not proven to cause miscarriage are sex, working outside the home (unless in a harmful environment) or moderate exercise.
Please do not think that you had do something to lead to this miscarriage. I totally understand how you feel right now. I was diagnosed with threatened miscarriage and me & my hubby are taking it easy as we had told ourselves that in the worst case scenario, if this baby does not stay, we will not be super emotional about it.. we will just move on and try for another one.
