Feeling Guilty😟

So I'm 19+1 weeks, due to morning sickness I've lost 8lbs. Well I believe morning sickness stopped for good lol it's been 3days since I last got sick. Now I'm feeling guilty for eating my three meals a day and for eating a cheese burger for dinner. I feel like I'm going to gain so much weight now that I'm not trowing up anymore. Is it bad or am I just over reacting??? I've been eating fruits n veggies to but I feel like I'm doing bad for eating.
