I so upset

I found out I was pregnant last week I didn't tell no one but SO due to the fact that I had an ectopic two months ago. Not even mom or my best friend know the he tells me today oh he told his sister from when I told him I'm like why would you do that I just feel like it's to soon for him to be telling anyone at least let me tell my mom and he's like oh  not gonna hide anything from my sister that not the point that was a private moment between me and you . Am I wrong for being upset
