sisters embarrassed

Dominique💕🖤
I'm 17 and pregnant. I'm like 14 weeks aka 4 months. I plan on attending the state fair this year even though it's in July so I'll be about in my 3rd trimester 23 weeks from my calculations. When I told my sister she automatically said "well I don't wanna be seen with you." So I'm like what do you mean. She's like "I'm not trynna get talked about by my friends because my teenage twin is pregnant". I kinda took offense to that because we always go together but now she's switching up on me. Should I be offended by this or understand where she's coming from?
