Ultrasound questions

Winnie
Hey so I have had almost 3 ultrasounds and in all 3 they said they cannot see any boy parts since the baby has its legs crossed all the time so they gave me 90% girl today I went in for an anatomy scan and the babies legs where closed again so she had to take a side view where she says it's likely a girl cause she sees no boy parts but also has not seen the girls part 100%. I asked her if I should buy pink and she said no we wait . Has that ever happened to anyone and had a boy or it's most likely girl? I really want to shop but I have second thoughts
