Im w7 d4, done 2 scan, i dont see anything in the sac. When ultrasound will see baby heartbeat?

Hi! When I’m week 6 I went for ultrasound scan also can’t tell for the baby heartbeat. So I went to another clinic to ease my mind which is the transvaginal ultrasound scan (to insert in) and straight away can see the flickering heartbeat. Hope it’s help! Don’t worries everything will be turn out fine. :)
