I just want it to be over

This is my first miscarriage, And I can't believe how awful it is, and I'm just at the emotional part. Been spotting for a week starting at 5 weeks. Saw nothing on the u/s last week, checked hormone levels and they went up. Went back in yesterday and u/s still showed nothing, and hormone levels hasn't gone up in 4 days, dropped a little even. Now I'm still only spotting and waiting for either a natural miscarriage to finally start or looking at an ectopic if my levels haven't started dropping dramatically in 48 hours. I'm absolutely heartbroken, and at this point since it's not a viable pregnancy, I just want it to end! And after reading so many other's stories, it seems like this is common... Why must it take so long?! It's like insult to injury. I don't know how so many woman handle going through this multiple times, I just feel completely shattered.
