Lost tampon? SOS

I'm very confused and a little embarrassed to have to put this in writing but here goes nothing. I went out to the bars with some friends the other night and when I got home I was absolutely exhausted and feeling like my period was so light that I didn't need to put another tampon in for bed because my flow is always really light when sleeping anyway. Well, when I woke up I started second guessing myself and panicking that I did end up putting another tampon in because I hadn't bled at all. Well, there was no tampon so I just figured my period was really light. It's been 2 days now and still no bleeding and id only been on the second day of my period when this night took place so it's not making any sense to me.... So now I'm panicking thinking somehow there is a tampon lost inside of me. I did some self searching (sorry if tmi) and didn't find anything but I'm worrying if it's possible that I wouldn't be able to find it?! I'm just freaking out so any advice would be really appreciated. Thanks all!
