HELP MISCARRIAGE

Elizabeth

Okay, so I found out I was pregnant about a month ago and they told me I was almost 5 weeks (I found out in the hospital so I had ultrasounds) then I had my other ultrasound almost a week ago they told me I was 6 weeks, but no heartbeat or anything so I know I'm having a miscarriage also I know because I've been bleeding with lots of blood clots but my question is how long can I bleed with blood clots coming out?! it's been happening for about 2 weeks and these clots can range from tiny to the size of a golf ball!!!!!!!!! how long can this happen for?!
