Ultrasound 12 week question

Sarah

Hello all you beautiful Feb 2020 Mamas! Quick question for those that have had their 11-13week scan, is it a vaginal ultrasound or abdominal? Which one did you feel was clearer if it makes a difference? Just want to know what to expect and whether or not to go full bladder or not (kinda difficult to hold a wee anyway lol). Any advice will be so appreciated x
