I m on my period and I always use tampons. While on the first couple hours of my period, I felt as though i was passing a blood clot, which I used to get a lot when I was 12-16, and it felt like it went straight through my tampon and right into my underwear. So I went to the bathroom and checked and instead of seeing blood, there was a pretty far amount of odorless clear watery fluid on my panties. This has never happened before and I m really confused. What could be the problem?
