Biopsy needed: Yes, if this is in fact a melanoma, a biopsy would still show it even though you pulled off the top layer. If it's not a melanoma, a diagnosis could still possibly be made. It would be uncommon for you to be able to simply pull off a melanoma however. See your dermatologist to be sure.

Tiny painless dark oval appeared on hand 3 days ago. Thought it was a blood blister but don't remember an injury. Should I get checked for melanoma?

Tiny painless dark oval appeared on hand 3 days ago. Thought it was a blood blister but don't remember an injury. Should I get checked for melanoma?

Bruise: Sounds most like a bruise and sometimes they can pop up without being aware of the injury. You can give it a week or 2 to resolve. I would give it up to a month to resolve. If it doesn't, you could see a doctor, but very unlikely to be melanoma.

However, without actually being able to see you clinically, we can't give you an accurate diagnosis. It should be gone in about one week. If it lasts more than two weeks, make sure you have it diagnosed by your dentist!

What does a blood blister in the mouth look like? Does it break open?

Firm and purple: If you bite your lip/cheek and traumatize inside your mouth, but not enough to break open the suface of skin (mucosa) then you may develop a firm purple-colored bump. Over time the "blood-blister" will pop and drain and should heal quickly. If it does not resolve within 7-10 days, have it checked out.
