Mixed feelings 😥

I’m currently 9 weeks and 3 days. Started spotting on Wednesday. Saw my doctor on Friday and baby looked perfect (her words.) The heartbeat was 174.

Fast forward to today....around lunch time I started passing clots and not small either. Went to the ER and once again baby was okay with a strong steady heartbeat and HGC was over 51,000. I definitely am so thankful baby is okay and had a beating heart but the clots still worry me. The fact they couldn’t tell me what caused it doesn’t help either. Anyone else experience this?!
