So i'm 15 and i normally have very irregular periods. I pretty much get one every 3 months but this time, I got it 2 weeks after my most rescent one. My flow is normally pretty light but this time it is super heavy and I really don't feel good. I feel light headed, tired, dizzy, and my hands are shaking for some reason. I decided to take a nap so I put on a fresh regular pad and napped for two hours, and it leaked because the pad was so full. Is this too much blood? I'm also experiencing large blood clots. I think I'm going to stay home from school tomorrow and if my flow is still that intense I'll go to the ER tomorrow night. I just don't want to go right now because I never know if this is just a one day thing, or if it will last the whole week. So then I bought the maxi pad and I wore that for 2 hours and it leaked.
