Well, I really wouldn't know much about being pregnant but i know about panic attacks and anxiety. All i can really say to you for now until people with more suitable experience to help you come online is that you will be ok. Hang in there. You should take time to explore this website. It has many tools that can help you. The CBT program is awesome. It is a twelve week program filled with information and tools that can really help you whatever the reason that set off your panic. I suggest you give it a try, it really helped me a lot. Anyway, Some people who have been pregnant before will come along to answer you better soon I am sure. But hang in there, my thoughts go out to you, I know panic attacks feel really aweful and feel free to write in here and vent and share your thoughts with us we are all here to help and support you as best we can :)
