Littlepooh, I suggested that you need to consult doctor asap. Passing out the 'liver-like' thing may not be good sign. I have similar situation 1 month back while I was bedresting at TMC...
Just came back from gynae... I was advised that we must see heartbeat by 6 weeks 3 days. If not, pregnancy will fail. Seems like mine doesn't work out well... very sad now.
Can you advise what you see during your ultrasound scan? I seems to have some issues with my pregnancy and want to understand what others can see when they are 6 weeks pregnant. Thanks.
