Suggest Remedy For Taking Out Tampon Stuck Inside Vagina

I am not sure if I have a tampon stuck inside of me or not! I went to use the bathroom and strained a bit and swear that I felt the tampon. After I used the bathroom before flushing I felt for the string to pull it out and felt nothing so I began to panic. Out of habit I flushed the toilet realizing later that it is possible that it may have fallen out. But wouldn't I feel that? Anyway, I have been pushing, squatting, washing my hands and feeling around and feel nothing! I have on a pad and feel my menstral now flowing. Is that because the tampon is so far inside of me or because it feel out while using the bathroom. I really don't want to spend hours in the er for nothing, but I also don't want to die from tss!!! Is there anything I can do from home before I head to the er to see if there is a tampon inside of me???!!! Please help!!!
