My husband uses his and it hasn't caused any problems for us.
The problem with e-cigarettes is that, so far, they are unregulated. This means they have not been tested officially to check their safety. As you're using one, you can't be sure what's in the vapour you're breathing in, or "vaping". This means that neither can you be sure which chemicals are reaching your unborn baby. E-cigarettes usually contain nicotine, water and propylene glycol, but they can contain other, hidden toxins.
Speak with your GyOB and they will give you more info on it.

Wat is ftm just wondering. And I don't think it will bother u.
Its vapor so its not as bad as secondhand smoke but those things still aren't healthy for you with all the chemicals so ask him to blow it away from you or don't sit next to him
