POSITIVE PT WITH YOLK SAC BUT NO BABY FOUND IN 6WEEKS AND 3DAYS

Nag pt ako ng oct 15 and positive sya. Nagpa trans V din ako may yolk sac but no baby seen 6weeks and 3days. And now im 7weeks and 2days. Is it normal na hindi nako madalas maihi or wala naki morning sickness. May sched ako for trans v after 3weeks. May same case ko din po ba dito? Medyo worried kasi ako 1st baby ko sana to. #pleasehelp #advicepls
