Thanks Smallfryplus and Cherished for your responses.

The reason I asked is that a friend of mine who underwent IVF was prescribed it as it assists with implantation, and can also reduce the risk of miscarriage. But it has to be baby aspirin (81mg max) as the adult dose is too strong and has harmful side effects in pg.

After hearing about it, I did some internet searching and found that it is thought to help the blood flow to the foetus and may assist in preventing a m/c as it stops clotting in the placenta and increases the blood flow to the womb; and because of the increased blood flow it can also help with conception.

It seems to be more widely used overseas than here though, that's why I was wondering if anyone here used it.
