<human>: Could you distill the essence of the text into 1-3 sentences?

So, girlfriend visits me from college after ~2 weeks of complaining about the worst period of her life, constant cramps, and back pains. He boobs went from B cups to 36c (don't know if that's relevant). We typically had a pretty active sex life. ~5 times a week.

This whole weekend, she wanted nothing to do with anything sexual. Any innuendo's or anything past kissing would turn her completely off. This was pretty unusual. Anyways, on the last day of her visit, she calls me crying and said that it was "unfair for me to not know".

I asked her what it is, and she explained to me that she is fairly certain she had a miscarriage. All the symptoms add up, and she took a pregnancy test which came out positive without me knowing.
I completely believe her, and that she had a miscarriage. I'm just all not that shook up about it. She is pretty devastated, and I'm being as supportive as I can be, but I'm just not devastated like she is. Sure, I'm shocked I almost became a father, but it just isnt the end of the world for me.
Should I be more concerned?
<bot>: She had a miscarriage, I'm not too worried, she is, feel like im not as shocked as I should be.
