Am I wrong to feel this way?

I announced my pregnancy on Facebook at 6 weeks... so two days ago. Then my sister in law posts the next day (yesterday) and, in a nutshell, basically says oh I am too, except I’m 12 weeks, here’s a sono. She did this to me on my sons pregnancy too. Is it wrong that I’m upset that she did it right after I did?
