My bff went through something similar. (Though she found out about her surprise pregnancy when she was terribly sick, ended up in the ER. She found out she was pregnant & it was ectopic so she landed in surgery a few hours later).
She went through a lot of different emotions in such a short time. Happy that her body finally got pregnant on it's own. Then disappointment at her body that the pregnancy wasn't viable. Then hopeful for the future. But then also, scared.
Go easy on yourself, I'm sure you feel a lot of emotions. They're all valid.
