Sec rejection

So my boyfriend has been complaining that ever since we have found out I was pregnant which was two weeks ago that we haven't had sex. I'm 5 weeks and a few days and I just have a low sex drive. But today I was going to have sex with him and he rejected me. I started crying because I just felt like maybe I'm ugly and fat and now he doesn't want me or that it only happens when he wants it but never when I want it. I just feel so down now... Normal? Any advice ?
