Oo, normal pa yan sa 7 months kasi maraming space pa ang baby para mag-turn inside, so don't worry too much! But it's best to mention it sa OB mo sa next checkup para ma-monitor niya, a few of my mum friends had breech babies at this stage tapos nag-turn na sila on their own before delivery, pero important na may eye on it ang doctor para alam ninyo what to expect as you progress.
