29 weeks and completely lost my appetite

[11weekstogo]

I have been eating fine up until now but I feel constantly full and if I eat something like a banana in the morning I can't eat anything else and don't get hungry for the rest of the day.
I'm forcing myself to eat small meals which I don't want and then feeling sick or uncomfortable after.
Has anyone else felt like this at this stage and with 11 weeks to go does it get worse?

Yeah I've had this at 30 weeks now - I think mentally I'm cautious of eating too much and getting painful heartburn, which has reduced my appetite! I've basically been snacking throughout the day instead of full meals (with healthy stuff - fruit, houmous with veg sticks and pitta, yoghurt, cereal, nuts).
