So my ex has posted a picture o Facebook of a supposed 8 week scan but she is shouting about how the ultrasound technician doesn't know how to do her job and she is in fact "in her eyes" 3 or 4 months but from this scan shown below can you tell how far she is gone, if she is pregnant at all or any other suggestions of what this blob can be, thanks. I know its an awful thing to ask but she has lied in the past and it all seems too coincidental
