Is it safe to use nebulizer if you're pregnant?

Hello sa mga mommies ntin dyan. It's my first pregnancy po and Im on my 11weeks now. Ngayon po kasi im suffering from cough, as in sobrang lala ng ubo ko which leads to severe asthma attacks. I visited my ob yesterday and nagresita lg sya ng Amoxicilin and Ambroxol. Pero my asthma attack is getting worst so I decided to nebulize kasi di ko na po talaga kaya. Sabi nya in 3 days na hindi pa mag lessen ang cough ko, balik ako sa kanya. So before nman ako nag nebulize nag google nman ako and a lot of results shows na it's safe naman daw po. Pero ask ko na rin dito kasi baka may mga asthmatic mommies din like me na may maitutulong or share their asthma experience while pregnant. Salamat po.
