Staying positive after the scariest moment yet!

I was 13 weeks & 6 days pregnant on Thursday April 28th, and around 545 PM CST, I had the most scariest pregnancy moment thus far......I started bleeding - ALOT.  It wasn't just a little bleed, it was like someone turned a faucet of blood on - no cramping however.  It happened so quickly that I initially thought I had peed myself (never had that happen before but it was my first thought).  I looked down and saw the blood dripping through my pants onto the kitchen floor and immediately thought the worse......that I was losing our perfect little baby that we loved so much already.  I tried SO hard to not cry and panic, but at that point it was impossible to not do.  I picked up the phone and called my husband, who thank God was in the driveway coming home.  I changed and he immediately drove me to the ER - which might I add was the longest drive ever.  They took me in right away and took blood samples, and then sent us back out to the waiting room to join about 40 other people.  For the next two hours we sat waiting to be called, and I continued to cry and think the worse.  I was devastated.....thinking "how could this have happened.....why me?!".  Finally our name was called.  We were escorted to a room where I was told to change, and wait some more.  An ER doctor finally came in after about an hour, introduced himself and performed an internal exam.  He discovered my cervix was still closed (THANK GOD - 1st good news).  He then said we'd need an ultrasound to see what's going on, and so we waited another 2-3 hours.  We were taken to an ultrasound room, where we finally got to see what was going on with our little miracle.  The baby had a perfect beating heart still, and everything else looked good inside.  I cannot tell you how overjoyed and overwhelmed with emotion we both were to see and hear a heartbeat of our baby, after thinking the worst.  We then waited to see the doctor again for the diagnosis, which wasn't exactly an answer......."Unexplained Hemorrhage".  Not exactly what we wanted to hear, or understood, but we knew our baby was alive and well.....and that's what mattered.  On Friday April 29th, I bled a little bit more, but nothing in comparison to the night before.  Around 8PM, I passed a blood clot about the size of a golf ball......never had any cramping.  After this happened, the blood stopped.
Today May 2nd, I had a follow up visit with my regular OB doctor, who took a look at my cervix which she said looked perfect - closed!  There was no more blood either which was another great sign.  She stated that sometimes "things are just unexplained in pregnancy, and this is one of them."  So it looks like I won't have a reason as to why this happened to me, but the baby is fine and that's what I should be focusing on.  
I cannot tell everyone how grateful we are to have so many thoughts and prayers for our little one during these extremely difficult few days.  We are truly blessed.  Please continue to keep our miracle in your thoughts and prayers moving forward, hoping this doesn't happen again.  
Much love - Kristina XO
