This is often a good time in your life to focus on you, unless this is your 2nd, 3rd or 4th pregnancy and you have other children to take care of in which case still try and make time just for you even if it is as simple as running yourself a bubble bath at the end of the day.
Find classes such as yoga, Pilates, fitness, birth preparation etc that will allow you to meet other pregnant mums providing you with some socialisation and a safe environment to share how you are feeling. It also gives you a nice network of women for once the babies are born.
Find some time in your day to just focus on your breath. It might be first thing in the morning when you wake up, at lunch time sat in the park or at bedtime. Get yourself in to a comfortable position. This might be lying down, seated, slumped over some cushions or standing. Listen to some calming music, follow a meditation app or just be in quietness. Take in deep breaths through the nose filling up the lungs, side to side, forward and back. Breathe out through the mouth exhaling every last bit of air and feel a sense of heaviness throughout the body. Continue to do this until your head feels clear and your body feels completely relaxed.
