Broken glass cut


I know this may be a dumb question but Im a little confused. Last night I came home and was sitting on my bed and cut myself on something, I looked down and realized I was bleeding and had a surface cut on my middle finger. I noticed a tiny piece of glass on my sheets right where I had cut my finger. It cut my finger like a papercut in two places but one of the cuts was a surface scrape and the other startes bleeding like a papercut after about 30 seconds. I have no idea where the glass could have come from, I cut myself after about 5-10 minutes after being home, maybe a little longer. I noticed that on the shard of glass if you hold it up to the light there is some trace blood on it so it freaked me out and made me wonder if someone else had cut themselves on it first or if that is my blood. Im just confused as to how it could be my blood if it didnt start bleeding until 30 seconds-1 min later. Afterwards I thoroughly washed my hands. Im concerned because I read this on a website. 
HBV and HIV are most commonly transmitted through:
• Sexual Contact
• Sharing of hypodermic needles
• Accidental puncture from contaminated needles, broken glass, or other sharps
• Contact between broken or damaged skin and infected body fluids
Accidental puncture from contaminated needles and other sharps can result in transmission.
In most work or laboratory situations, transmission is most likely to occur because of accidental puncture from contaminated needles, broken glass, or other sharps;

Im basically wondering if Im at risk for getting HIV from cutting my finger on this random piece of glass? If there was someone elses blood on it that had HIV would it die quickly when exposed to oxygen or could this put me at risk? That info on the website kindve confused me and made me paranoid because I dont know where the glass came from and Im so worried now I cant think about anything else.

Thank you so much doctor, I will put this silly worry behind me and move forward, I guess I just needed an expert's opinion and judgment on this because reading things online can be confusing and taken out of context. I read through some of your other responses to people and I just want to say I hope you know how helpful you are to people in providing detailed, concise responses and educating people/lessening anxiety with your expert and honest knowledge. I hope you have a great week! Thanks again.

Yes even if it were someones elses blood (not a realistic concern however), you would not be at risk. EWH

Thanks so much for that quick and helpful response. Just one more question to clear my anxiety...if for some reason it was someone else's blood that had HIV would I be safe anyways even though I cut myself with it? Like would the virus likely have died at that point on the shard of glass because it had been exposed to the air for atleast 10-20 minutes? Sorry for the final question I just have bad anxiety and would like to completely put this worry out of my mind and I trust your response.

Welcome to the Forum. I would disagree with the information you got from the web site regarding broken glass.  Broken glass and used needles are two entirely different things and have different risks associated with them.  The problem with used needles is that blood can be in the hollow portion of a needle, protected from the environment and therefore allowing the virus to live longer until it punctures deep into tissue to cause infection.

In the other hand, glass fragments are solid. As a result there is no protected site for blood to be sheltered from the environment. As a result the virus dies quickly in the environment.  Further, in the situation you describe, the blood you describe is likely yours.   Sometimes bleeding takes a little while to start, in part because the glass blocks the bleeding and in part because it takes a while for the bleeding to start.

Bottom line, there really is not reason for you to worry about this.   No need for worry, no need for testing.  I hope your finger feels better.  EWH
