I love pre-natal yoga! I live in southern NH so I go to the Yoga Tree in Haverhill. It's $70 for 6 sessions. Probably any good yoga studio that offers prenatal yoga will be fine. I had never taken a class before, but they focus a lot on breathing. They will explain a variety of ways to do a pose based on your abilty/comfort. Class always begins with telling everybody about your pregnancy and whatever your latest symptoms or news may be. And they end with a restful meditation on a big comfy pillow thing and give you a quick little message with lavender oil. It really does help you to disconnect from the outside and focus on yourself. I sleep like a baby every Tuesday now, looove it.
Wentworth Douglass Hospital in Dover, NH offers a Prenatal Yoga Class. I went during my pregnancy and loved it. You could check in with your local hospital. Also I found this: https://www.doverdoula.com/Dover_Doula_prenatal_yoga.html
