Is there any proof that toxins in the home can lead to miscarraige?

I don’t think there is a link. Sad to say, but, lots of women have miscarriages. The reasons are numerous, but in the end, it is really just that the fetus couldn’t survive for some reason (most commonly a genetic problem in the fetus).

I was shocked to find out that up to 10–25% of pregnancies end in miscarriage (source)... I guess it’s just something that isn’t talked about when it happens.

I think it would be less painful for those that have to go through it if they knew it was so common up front.

I don’t think it has anything to do with the other.
I’ve had multiple miscarriages, and they do just happen…nothing you can do to prevent them, unless there’s a physical reason.

Many many things can cause miscarriages, so it would be hard to know what the case was with your friend. I also don’t know if there are any studies looking at the environment human women are living in compared to miscarriage rate, but it is clear that exposure to chemicals and other environmental differences can cause birth defects, some of which are lethal and result in a miscarriage. Most studies on this are done with non-humans (for obvious reasons) which actually makes it hard to classify a lot of substances as harmful, because we really don’t know. If you want to read more about it, read up on teratogenesis, which is an environmental assault on normal development, and teratogenic agents which cause birth defects. (Or, if you don’t want to be too scared to ever get pregnant, DON’T look it up! I swear if I get pregnant I’m going to be terrified to touch or eat anything after the teratogenesis chapter in this Ecological Developmental Biology textbook I just finished…)

Part of why I was wondering was because I read “Marley and me” (cheezy plane book) and the woman in the story suspected that she may have miscarried because she had flea bombed her house…..seems to make sense. It would be really nice if we could just say to my friend of friend “get rid of the lysol and you’ll be okay.” Obviously she is heartbroken and wants to conceive again soon.
