Lower Abdomen

Good day mommies. Recently found out I am pregnant about 4 months ago. On my first pre-natal check up they did a scan I was 10 weeks and they said that baby is in a breech position. Last week they said that the baby is still in a breech position, now the problem I am having lower abdominal pains when I am sitting for too long and I also have a hard time when I have to walk becoz the baby is in the breech position. Should I be worried?
