Im 15 weeks pregnant, i live next to a sewage plant.in the early morning and evening it smell very bad! make me feel very sick...what can i do?

So Sorry! : Oh, that sounds miserable. Pregnant women are definitely more sensitive to smells than non-pregnant women, and to have that smell bothering you. There's, of course, not much you can do. There are medications for nausea if that's an issue for you. Talk to doctor about treatment for nausea if that's a concern. Other than covering up smell (lemon often works) you can't take it out of the air.
