It was planned to exclude those who did not accept to participate in the study, who were diagnosed with risky pregnancy, who were illiterate, who had systemic disease and mental problems requiring treatment, who had a gestational week less than 26-28, and who had communication and language problems. After the sampling is completed, the aims of the study will be explained to all pregnant women and they will be included in the study if they are satisfied. Participants in the experimental group will start the first pregnancy yoga session between the 26th and 28th weeks of pregnancy and attend the last session at the 37th week of pregnancy. They will practice yoga twice a week (each session lasting 75 minutes) in childbirth preparation classes

The control group will receive the routine antenatal care that all pregnant women receive.

In the experimental group, yoga exercises were performed for 50 minutes with physical yoga movements (Vrksasana (tree pose), janusirsasana (head-knee pose), modifiedmarichyasana (great sage pose), baddhakonasana (connected angle pose), malasana (garland pose), sukhasana (meditation pose), ardhapadmasana (lotus sitting pose), gomukhasana (cow face pose), supta matyendrasana (spinal rotation pose on the back), bharmanasana (table pose), chakravasana (cat/cow pose), dandayamanabharmasana (balancing yoga pose), vajrasana (diamond pose), viraphadrasana 1-2 (warrior 1-2 pose). The class will include 15 minutes of meditation (deep relaxation with a focus on breath and self-awareness), breathing exercises in between and 10 minutes of relaxation.

In order to evaluate birth satisfaction, the Birth Satisfaction Scale Revised form (BSS-R) developed by a researcher was adapted into Turkish and a validity and reliability study was conducted. The BSS-R is a 5-point Likert-type scale. It is scored as strongly disagree '0 points', disagree '1 point', undecided '2 points', agree '3 points', strongly agree '4 points'. The lowest score of 0 and the highest score of 40 points can be obtained from the scale. In the scale, 6 statements are positive, 4 statements are negative and 4 items are reverse scored. The reverse scored items are items 2, 4, 7, 8. The higher the score obtained from the scale, the higher the woman's satisfaction with childbirth. In this study, the Cronbach's alpha reliability coefficients of the scale were 0.72 for BSS-R total, 0.78 for 'Quality of Care Services', 0.71 for 'Stress Experienced in Trauma', and 0.70 for 'Personal Characteristics of Women'.

The scale was developed to determine the birth preferences of pregnant women based on the Health Belief Model and Planned Behaviour Model. The Turkish validity and reliability study was conducted. The scale is suitable for naturally pregnant women without systemic and psychiatric diseases. The scale consists of 18 items in total and three sub-dimensions (self-efficacy, normative beliefs, preferences). The scale form is 5-point Likert type. Each item in the scale is scored on the options of Strongly Disagree (1), Disagree (2), Undecided (3), Agree (4) and Strongly Agree (5).
