Asthma while pregnant

Can anyone give me pointers on how to deal with asthma attacks and exacerbation while pregnant? I no longer have Medicaid due to me moving out of state. I am coming up with the documents to get Medicaid where I now reside. That will take awhile. In the meantime I am having asthma exacerbation. I have a nebulizer and fill it with 2.5mg of albuterol. I take it every 4-6 hours. I’ve been feeling chest pain for the past week or so now. I especially feel the pain while sleeping even when I prop myself up to go to sleep. I’ve been taking 650 of Tylenol since my last asthma attack several days ago. I’m tempted to take more Tylenol a day but I limit myself because I don’t want my baby to end up with autism or adhd. I’ve read some research about Tylenol and taking it while pregnant. Anyways, I’m just trying to avoid the ER and a big bill. Any pointers and suggestions will be appreciated! Please no rude comments.
