Hi, I have suffered from Anxiety and Panic for several years. Sometimes the panic and anxiety are worse than others. I have truthfully found that since becoming pregnant with last child and with this child that pregnancy seems to make the panic and anxiety worse. The way that I handle this is medication free. I try to talk with my husband, mother, or someone else whn I feel panicky or anxious. If I have a strong support person there for me to tell me that "I am okay" I am fine. If I do not have that person there I simply try and regulate my breathing and emind myself that it is simply a chemical misfire in my brain, which is exactally what panic and anxiety are, and I remind myself that I am pregnant and that it is not good for the baby for me to be having the panic attack. I also remind myself that I am okay and not dying and will be okay. Sorry this is so long but I hope this helps.
P.S. By the way my last child was full-term and suffered nothing from the panic attacks and this time I am now 4 moths along and having no probs. with the pregnancy due to panic.
Good Luck, and you will do fine.
