Is my reaction normal?

Last Friday I found out I was pregnant. I was spotting Thursday and thought maybe it was implantation. By Sunday, I hadn't stopped so I was told to go to the ER... Long story short, I lost the baby. I was almost 6 weeks.

I was excited for this baby. I cried Friday and most of Saturday unsure how to feel about having another child, but by Saturday night I was ecstatic. I was so happy. I couldn't wait to start planning... When I saw all the blood, I started hyperventilating... I couldn't handle the grief... Ive spent the last 3 days just laying down, cramping and bleeding. I'm almost done with it but... This is so surreal... Everyone's carrying on with life and I don't even know what just happened... I was told by the doctor something could've been wrong with it and my body rejected it... That it's so common now.... My body feels frozen. I feel sad inside. I feel awful but at the same time I feel like I don't understand what's happening. And I feel like I just have to keep going like I didn't just lose a child. I didn't just lose the chance of being a mom again... I'm thankful and happy with the child I have... I just don't know what's going on .. I am going back to work tomorrow and I'm not telling anyone but I don't know what to do because I still want to cry my eyes out but I feel like I don't understand why. I don't know if this explanation even makes sense... I'm so sorry for any mother who has had to feel this grief.... My heart goes out to you ❤️
