gender confused.. please helpppp

Samantha
Ok ladies I went today for my gender scan. I am 15 weeks today and the lady told us she saw 3 tiny dots in a straight line.... My daughter (age 6 now) had very visible 3 LINES... But on this baby today the umbilical stayed right in between the legs and the baby's feet were crossed, in the ultrasound pic I see neither honestly.... Tell me what you think 
(Red line I drew is the umbilical cord) ( where the arrow is pointing is the "3 dots")
