Boy or Girl?

Megan

I'm 16 weeks 2 days and I had my ultrasound today. Granted in my opinion, it was terrible quality and I waited 40 minutes from my schedules appt time for a less than 2 minute ultrasound. I asked about the sex of the baby, and my OB said she did not see any indication of the baby being a boy (no visible penis). Is 16 weeks too early to know or is it safe to assume baby is a girl?

*no pics because the ultrasound was such terrible quality.
