Awful symptoms

Hi everyone, I was just wondering if anyone is still having morning sickness and tiredness all the time? All I seem to be doing is sleeping or lying in bed; this is so unlike me. I have a feeling my iron levels may have dropped I've got more bloods on Monday. Also the sickness, I haven't eaten anything now and kept it down in over 48 hours, any recommendations on something I could try to eat? I just feel so awful. I've been in an out of hospital because I keep fainting all the time. They couldn't take bloods last week because my veins collapsed and no blood would come out, I'm 14 weeks pregnant and I just feel horrendous :(
