Want to scream...

I just need to get this off my chest.. And I don't know who else to turn to. Two weeks ago my husband and I found out i was 5 weeks pregnant after trying for a year and a half.. We were so excited! We couldn't believe that after trying for so long we finally we're going to have a baby! I told my mom because she's the closest person to me and we couldn't contain our news. We didn't want to wait so long to tell our family! Two weeks go by with no problems, I completely cut out all caffeine, started drinking tons of water, and doing everything I could to make sure I was being healthy for this baby. Saturday night I started experiencing some spotting and freaked out. I didn't remember having this with my daughter, so I asked my friend about it, and she said it was normal. Sunday comes, still having some light spotting. Monday rolls around and the light pink spotting has turned into bright red spotting. I knew this wasn't right. I asked my husband if he would take me to the ER so I could have some peace of mind, so we went. 4 hours into waiting I got up to use the restroom and it happened. My underwear was completely soaked with blood, and I was having dark red with bad clotting. I came out of the bathroom crying and telling my husband something was wrong, that it's happening!! He told the nurse and they finally called me back.. After running blood tests, ultrasound and transvaginal tests, the doctor came back. My hormone level was at 500... Either I was way earlier in my pregnancy than I expected or, at the end of a miscarriage, and by the amount of bleeding I was having, it was likely the latter. I immediately broke down in sobs, wondering what I could have done differently to prevent this? I thought I was doing everything right! And the doctor held my hand and told me over and over it wasn't my fault. No matter what I did, no matter what precautions I took, it would've happened if it was meant to happen.
