I Am 11dp5dt And I Started Bleeding At 8dp5dt. I

I am 11dp5dt and I started bleeding at 8dp5dt. I have had heavy bleeding with cramps and passing clots. Yesterday I was sure I miscarried. My level was 44 7dpt and today they are 206 even with bleeding. My levels are rising appropriately but could it be possible that you can bleed that much and still have a viable pregnancy? I'm also on crinone which I have heard can cause bleeding. I'm just so confused and worried!!!
