Miscarriage and now what????

Warning: Do not read if you have weak stomach.

So, even the miscarriage has been a rollercoaster nightmare.

Physically: Went to doctor on Thursday for ultrasound and blood draw. US was inconclusive as everything still looked ok and HCG still at 1507. Well, immediately following the appointment I started to drop blood clots...and various other things. Spent most of Thursday and Thursday night on toilet. Was filling, rather over-filling pads like crazy. Had huge pieces of I don't know what coming out. I would usually have a 5 second warning to run to bathroom. Most of the time I made it, but sometimes not. By Friday morning, I had lost so much blood that I was starting to get concerned and called doctor. They said what I was experiencing was not normal and had to go back again on Friday. Spent 2.5 hours in the office and filled 3 pads during that time. When the doc finally came in and I stood up to take off pad for US, blood came spilling out all over the floor, running down my legs and onto my feet. It was horrible. US showed more material still in there, but HCG had finally started to drop and was now at 947. Funny how we were so anxious to have that number go up and now we are waiting for it to go down. Doctor started me on meds to contract uterus and hopefully control bleeding. Well, it didn't work at first as Friday night was just as bad. Up every 2 hours with clots and full pads. So, back to doctor again on Saturday for another HCG check - down to 492 now and finally some relief from the bleeding as it was now at a manageable level. By Saturday night I felt ok enough to leave the house and it's gotten better since. I think the worst is finally over. Follow-up appointment with doc on Friday to check HCG again and talk about the cycle and next steps.

Emotionally: I've been a mess - sad, angry, disappointed, frustrated, rageful, jealous, depressed. Woke up this morning with a huge empty pit in my stomach. I just can't believe this is how it ended up. We were so hopeful that this was our miracle baby...or babies. We have believed so faithfully that we were meant to be pregnant and parent a baby together...our baby. It is so hard to not know why this hasn't worked for us. What are we doing wrong? Why do others seem to get pregnant so easily and have no problems? We've been to parks the last 2 days to relax in the sun and all I seem to see is pregnant women and families with babies and children. Everyone except us.

I've begun to think about other options and none of them are appealling. Our options - in no particular order:
1) Try IVF again (another $15K, that we don't have, and no guarantees)
2) Try IVF with donor egg/sperm (likely even more expensive and what's the point if not biologically ours and still risk of miscarriage)
3) Adopt embryos (much less expensive, but still not "ours" and no guarantees here either)
4) Adoption (seems like such a daunting process and not appealing to either of us)
5) No children (I just can't accept going the rest of my life without experiencing being a mother)

What do we do????
