|Her doctor's office cannot give you any information about her. Thats what hipaa laws are about - medical privacy. Why don't you go to the doctor with her?
Those pictures don't mean anything. They don't mean pregnancy, although by the looks of them, it appears she is 7 or 8 months pregnant.
Tell her, straight out, if you don't have proof, you'll assume she is lying. At that point, do not speak to her, don't take her phone calls, etc. She'll come up with some proof or admit it is a lie.
|...I have been very supportive, sending what I can to her and asking questions on this behave...|
|Oh. Yeah, I'd push my stomach out too if that's all it'd take to get some money.
Stop rewarding her behavior. She can prove a pregnancy to you very easily. If she's making excuses not to and everyone else is saying she's not, you're throwing money and attention at a liar.
