How do I know if I ate glass?

Alright, so I have these glass roses where I keep all my glass cups. One of the pedals popped off, and I’m really unsure if some shards came off with it. I found the pedals in one of the glasses, and didn’t see any shards in all the other glasses. I drank out of one of the glasses after washing it out and inspecting it thoroughly, but being me the worrier, I still am concerned if I swallowed even the tiniest shard. How do I know if I swallowed glass? I didn’t feel anything going down, and I have no pains in my stomach.

Thanks.
