I know someone personally (in my family) that was taking medication for a health problem. Had no idea it was a blood thinner and failed to tell the dentist. She ended up in the ER because blood thinners can cause excessive bleeding! Talk about scary.
I sent you a DM. I am not sure what the rules are for sharing clinics publicly and don't want to get into any trouble on the forum
If you have any other questions, feel free to ask there or in here.
