Tampon not expanding


So I don’t usually wear tampons •• every time I have tried regulars it feels like I can’t get it in far enough and it’s uncomfortable and it hurts, but I found a light tampon at Target and decided to try it today. I had it in for 8 hours and there was one point when a little leaked out but I was really dry down there by the time it was time to take the tampon out- like my vagina has not been that dry like ever. Any way, i went to pull out my tampon but it didn’t expand. It had blood on the outside but it had not really soaked up blood much. Am I doing something wrong or is my flow just not heavy enough?
