Eating making all day sickness worse


Is it just me or am I not alone? I'm usually OK most of the day than I eat and feel OK but as soon as I'm done like 5 minutes later I feel really sick I'm 9 weeks pregnant and after that I can't eat for the rest of the day and force myself to eat something so I don't starve the baby. I tried taking vitamin b6 like my Dr said but it doesn't do much. Sorry for the rant I just can't take it anymore. And the sucky part is I can't puke no matter how hard I try (only could once) so I'm just nauseous pretty much most of the day. And to top it off ive been getting headaches /low fevers almost daily or every other day.
