Watery period???

Kerry A

Started my period 2 days ago, yesterday was really heavy with quite a bit of clotting and really bad period pains (nothing to unusual) but I also seem to have clear fluid coming out?? A lot of fluid. Today my period isn't as heavy but still a lot of fluid and serious cramps. In the last hour I've had to change my underwear twice as there soaked even though I've got a tampon in? Anyone ever had this before? Activity ttc x
