Any way to prevent miscarriages...? ๐Ÿ˜ž

Just had my second chemical over the past few months, following a silent miscarriage in jan at 10 weeks, have made it to 5 weeks. I can obviously get pregnant, itโ€™s STAYING pregnant seems to be the problem. I know there are other women out there much more unlucky than we have been. Itโ€™s gutting...

And as an aside, my sister announced (through my mum) that she is pregnant with her third, BY ACCIDENT and just going to โ€˜try and deal with it...!โ€™

Makes me mad!

Any advice would be greatly welcomed ๐Ÿ˜Š
