Hi Girls,
The information about this is a bit up in the air Ive found. Some say not to do this unless recommened by your fertility specialist or doctor.
You are correct in the dose being very low at 81mg. It it supposed to be helpful by aid ing in implantation of the egg in the uterine wall, and for producing a positive effect on blood flow to the placenta. It may aid in reducing preeclampsia as well.

Yet there was an article which said that Pregnant women who take certain types of painkillers, including aspirin, are up to 80 per cent more likely to miscarry. BUT this study was only of 1000 women.

The new study which you might have read about had only started this year and it going to contuine for the next 5 years and will have around 1600 women.
