Has H insisted on a copy of her medical records proving she's pregnant? I know it sounds awful, but if she cannot produce them (ie if she's not pregnant) then she can't keep ruining your pregnancy by yanking H around.
If she can't come up with proof - he cuts off all contact. She can ask for a paternity test after she delivers. (IF she delivers). Don't waste another moment of emotional energy until she proves she's pregnant.
Meanwhile - you be careful, okay? This woman sounds freaky enough she could turn into one of those psychos who cuts pregnant women open to get their baby, YKWIM???
