Learning to swim while pregnant

Hello, I was only a month in of learning to swim as an adult when I learned I was pregnant.  I really don't want to stop with my lessons because it was my hope that I'll finally learn to swim this year. However,  I worry about continuing as im not great at breathing freestyle  (meaning right now i can not make it the length of the pool swimming freestyle without stopping if i do not have on fins). I'm better at backstroke but i am usually out of breathe after swimming one length.
