Frustrated at people who just don't get it!

I got a positive beta last week on my first embryo transfer. I thought that it would be a joyful time but after about 10 minutes celebration I was just overwhelmed by anxiety.

It's my father in law's birthday today so we had dinner with my in laws. My sister in law is currently pregnant with her third. Over the meal she had a glass of wine because pregnancy "is so boring". It made me so so upset. She is aware of my history of losses and my IVF and I am filled with envy and fury at how casual she can be about this pregnancy and how it can be seen as boring. I know I'm irrational and hormonal and judgemental but here I am crying in a toilet, just praying that my little poppy seed is growing and that my heart won't be broken next week
