Alright ladies.  I'm having some serious anxiety over here.  I'm so confused.  How can bloodwork and a sono (top picture here) show girl.  Then go back 2 weeks later for a repeat anatomy scan and get a surprise, boy!! (Bottom picture)   I just don't understand how it can clearly show girl, like where was his little wiener if it was a boy?!  Hahaha
I keep having thoughts and dreams that this is a sign and there are twins.   Is that possible?!  Like wouldn't they have realized there were two by now?   One twin couldn't hide that long, could it?  That doesn't happen, right?!   😂
