when you say its soaking through a pad or tampon so quickly, what absorbency are you using? my flow is usually pretty light but occasionally it will get heavy. but since i'm expecting it to be light i'll put in a light tampon and an hour later i have to switch to a higher absorbency because it's soaked through. if thats not the case with you though, and you're already using higher absorbency products, it can't hurt to call your dr. aside from the heavy bleeding you're not used to, are you experiencing any other symptoms or anything to lead you to believe it could be something other than your period?
I am already using super plus tampons and a regular absorbent pad(with wings),but why I'm considering this unusal was because I had just finished my normal period less then 11 days earlier and that was longer than usual but not as heavy as this one is.Nothing other than the flow is irregular, if I had more concerns I would have gone to a walk-in.My family doctor is an hr away so very inconvenient.
