Is he right?

So, I'm currently pregnant. With my first baby, and I found out I'm pre diabetic. So diet and insulin for me for this pregnancy. From my understanding, my doctor is going to want to see me a week after I take some sort of diabetic class. And maybe every week at that. Anyway, my fiance who just started a new job (thank God) after being unemployed for a month, quickly tells me that I can't be going to every appointment. There's no need for it. He tells me that after I tell him, how I scheduled the class and that my dr my want to start seeing me weekly, because of the diabetes and well to check on the baby. He then said that, if the baby is good one week, then he/she should be good the following week. So no need for me to have to leave work early, or miss a day.. I think he felt pressured because I asked him if he can handle stepping up a little bit, meaning my hours won't be all that great from work.. But I mean, then what am I suppose to do? I already feel bad that I have to inject insulin. And really I just want to make sure baby is okay. He kinda made me upset, made me feel like he's not supportive enough. All these tests that I have done or have to do, I go on my own. And all he hears are the results or just how my day went.. One day, when I was explaining the probability of me having to schedule an appointment with a high risk dr and diabetic specialist. He pretty much signaled me to be quite and stop talking, I get that he doesn't want to hear the negative stuff. But who else am I suppose to talk to? I just feel alone. But is he right about me not having to go to every appointment? Sorry for long post, venting and need some sort of advice.. This is my first pregnancy, With diabetes. And I don't know what to do or how to feel...
