Lovemy4... I **think** what everyone is guessing on is not what you and I both circled, but right under it you can vaguely see the fork of a nub, and like everyone said its not very clear.
Its going to be verrryyyyy interesting at 16 weeks. 
I truly appreciate everyone taking the time to look and will be sure to update....and not paint the nursery yet haha!
Thank you.
