Boyfriend thinks I’m starving myself while pregnant

My boyfriend kinda hurt my feelings earlier. I’ve always struggled with my weight and appearance I was always skinny my whole life before we had kids. I’m not considered big but I’m a lot bigger than I used to be and it bothers me I’ve always said I’d like to lose weight but I’m never able to lose a whole lot. I’m currently 5 months pregnant with our 3rd baby. I eat plenty in my opinion, I eat when I’m hungry and stop when I’m full. There are times that I don’t want to eat or I’ll skip dinner every once in a while because I still have some occasional lingering nausea but any time that happens I at least will try to snack on something and eat when I feel better. I had a doctor appointment today my bf stayed home with our other kids while I went alone. They weigh me at every appointment and I’ve lost a bit of weight. I didn’t think it was a big deal because I’ve lost weight with all my pregnancies at some point during them, I still have time to gain it back but he asked how the appointment went when I got home I told him baby was good I was good I’ve lost some weight etc I was just telling him everything about the appointment and a few mins later he started talking about how I have to start eating more and he knows how I feel about my body and sees me skipping meals or eating small amounts trying to “make myself lose weight” and said being pregnant isn’t the time to “starve myself” that he doesn’t care if I don’t wanna eat or take care of myself after the baby is born but that I’m not gonna “starve his baby just to lose weight” like he borderline chewed me out over losing weight and acted like I did it on purpose or something? I didn’t even know what to say I honestly felt almost embarrassed because he’s NEVER talked about my weight or anything like that. He was even comparing me to all my sisters saying im smaller than all of them even though i should be bigger than them since im 5 months pregnant and said I need to start eating for 2 now etc i just didn’t say anything and walked off because he hurt my feelings. He apologized later but now I feel like he’s been paying attention to my eating habits and stuff all this time and now im gonna feel self conscious about it and forcing myself to eat more. I can’t help that I’m losing weight and I’m definitely not doing it on purpose or starving myself while I’m pregnant I would never do something like that and it kinda offended me that he would even think that
