My First Experience, Assist me to soothe me ?

Hi mommies. Just to share with you my current situation. I checked on prgnancy test last week, it waa positive. Then up until now, after i did my scanning yesterday, doctor can't spot anything even the kantung. Yes i received options kind of advices. It's either tarikh subur sy lari then tak accurate with last period duration, @ probability luar rahim. Bcs frm doc's calculation according to my last period. My baby is already 6weeks in womb. Hmm risau. Scan tak nampak apa. Share me advices & good vibes. Nk kuatkan semangat sampai next scan on 10th. ?
