Always hungry 😫

I'm 11 weeks today and thankfully morning sickness has gone (touch wood) however now I have my appetite back... I eat something and straight afterwards I still feel hungry. My stomach is rumbling and I just can't get full! I'm literally going to be the size of a house if this continues. Healthy food seems to be the worst... It's like I haven't eaten anything and then the unhealthy food will last at least an hour.
