Currently going through a miscarriage Updated

I started lightly bleeding Tuesday night up until Sunday Morning. By Sunday afternoon, I started bleeding heavily and have been passing clots. I've passed about 3 huge clots but mostly medium sized. I've been feeling really weak and dizzy. I feel like I am losing a lot of blood. Is this normal. I was about 8 weeks along. It is Monday and I still have cramps (not as bad) but I am still passing clots and bleeding a good amount. I was thinking of going to the ER tonight if it doesn't slow down. I am exhausted, everytime I stand I feel like I am going to pass out.

Update: thank you, everyone! I am so sorry for your losses and the pain you had to go through. I did not go to the ER. I hadn't been eating or drinking because of the physical and emotional pain. My husband had me eat and drink and rest. I passed about 2 more small blood clots. It is Tuesday morning now. The bleeding has slowed to a light period. My body is still tired and emotionally I am a wreck. I will keep an eye out for anything strange. Hope you all have a wonderful holiday!
