That sounds awful Amps! Hope they are able to pump you full of good things to sustain you and belly bean for now. Congrats on being 17 weeks!!
Spidery, don't be too alarmed with symptoms. I didn't have any really either. For me they came and wents, but usually it wasn't much. It is stressful though, can totally understand where you're coming from. Try to trust your body is doing its thing.
