No. It doesn't mean anything for the baby. It was just the doctor/sonographer talking out loud. They can see the 'corpus luteum' on the ovary you ovulated from. It remains large during the 1st trimester & secretes hormones to make your endometrium grow-grow-grow to nurture bub. After the 1st trimester, the placenta will produce the hormones & the corpus luteum isn't needed (it will shrink away or burst). cool eh?
