Miscarriage question

I hope I don’t sound insensitive.

I had a still born baby in the past and currently 8.5 weeks pregnant (haven’t had my first scan-next week). So I am unsure of how a miscarriage feels or starts. I am super nervous about this pregnancy now and was curious. When your miscarriage started did it start with blood or cramps?? Just wanting to know what to watch for. Thanks in advance and sorry for your miscarriage

Unsure of which group to post this in so if o have the wrong group let me know ;)
