Uy, congrats on the pregnancy, momma! I don't have personal experience with asthma during delivery, but honestly, this is something you really need to talk to your OB about, asthma can affect labor differently for each person, and your doctor needs to know your severity level at least, kasi may adjustments na pwedeng gawin. A few of my mum friends with asthma delivered normally naman, pero ang management and prep nila was based sa advice ng doctors nila talaga, so don't stress pero make sure to bring it up sa next check-up para ma-plan ninyo together, okay?
