子宮 (shikyuu) is the standard anatomical term and safe for any context. 母胎 (botai) and 胎内 (tainai) are more literary and often used in poetic, spiritual, or metaphorical expressions. 母胎 emphasizes the mother's body, while 胎内 focuses on the interior space.
In everyday conversation, Japanese speakers rarely use poetic terms like 母胎 unless speaking metaphorically. Stick to 子宮 for medical or factual statements, and use お腹 (onaka, belly) for casual pregnancy talk (e.g., お腹の赤ちゃん for 'baby in the womb').
