What does it mean?

Hi mamsies. Anyone ever had an encounter wherein na-IE kayo ni OB and then after a while she said "parang may laman, so kelangan kita ipa-ultrasound"..? I am very much confused and worried. Baka kasi it's something serious. Tomorrow pa ang schedule ko for ultrasound. And no, as far as I know di naman ako preggers and was just there for my reproductive health check up.
