Hard time eating meals...

So this is my second pregnancy. First I ate everything in site! This time I can hardly eat! My body has gone through a lot this time even though the baby is fine. I am never in the mood to eat and it always gets to me feeling weak. I'm 26 weeks and gained about 10 lbs. I'm not complaining about the lesser weight gain but I do want to eat and make sure the baby is getting what she needs! Any suggestions? Or anyone else going through this?
