Hey there, Welbutrin is known for causing anxiety until you are used to the medication. You may try taking the med in the morning not at bedtime or talk with your physician about a different medication.
Xanax is frequently not chosen for someone who is pregnant.
BuSpar is generally considered safe for pregnant women. Perhaps you would like to ask you physician about using this med. I use this med and it helps my anxiety.
Take care and be safe.
It sure is worth asking your physician about. Sorry to hear you were allergic to Buspar. I do believe you can find something that will help you and still be OK with your pregnancy.
Take care and keep on talking to us.
