I started my period last week and it's going past 5 days. I had pretty heavy blood flow, I would change my pad in 2 & 4 period. Now is the time I'm supposed to stop, it's thinner but I still have to wear a pad. I can go all day with 1 pad though. Is this normal? I'm getting a little worried ( I started my period on Wednesday night last week and it's Wednesday night now)
