Loss #4

Just need to let this out, so I apologize in advance if this turns out kind of long. I'm currently going through loss #4. This is my 5th pregnancy overall. After giving birth to a beautiful healthy baby boy on Aug. 7, 2006 I have had problems ttc. In 2012 i found out i was was pregnant after an easy care free pregnancy with my son i expected the same with #2 however at 10 weeks I began cramping and spotting which progressively for worse called the dr and went in immediately. After not finding a heartbeat on doppler for sent for an ultrasound to which I found out it was an ectopic in my right tube. Tried treating with methotrexate which failed. Tube ruptured less than 24hrs later resulting in emergency surgery to have it removed. Fast forward to April 2015 pregnant again. This time called the dr got hcg checked right away. Levels were low. Rechecked 2 days later and they did not double. Dr informed me it was a chemical. Miscarried 2 days later. Sept 2015 pregnant again. After several hcg checks and hcg not rising normally dr ordered an ultrasound and at what would've been 8 weeks was officially told pregnancy was "unknown location". Treated again with methotrexate. Now here we are after 5 years of ttc. And basically giving up all hope of ever becoming pregnant I ended up in the emergency room for chest pain. Was asked the "any chance you could be pregnant?" I say very little to no chance... few hours later. While doctors at the e.r ate still awaiting tests to come back doctor comes in... tells me all my blood work is normal except for 1. Come to.find out I'm pregnant. Now for the 5th time. First I was excited which almost immediately turned into anxiety and fear of another pregnancy loss. But just being pregnant gave me hope. Based upon lmp I would've been right at 4 weeks. Hcg was 149. Called dr. Friday dr wanted me checked right away given my history however I was not able to get in that day. Did recheck of hcg on monday. Hcg was 322... dr was not completely happy with the rise but said that it was still within normal range so she wanted a recheck in 2 days. Yesterday went in for blood draw. And 930am I got that dreaded phone call from the doctor. Hcg level has dropped from 322 to 98. I broke down on the phone with the nurse started bawling. Asked if there was a possibility there was an error. I still feel pregnant. I have no cramping no pain and have had very minimal spotting a week ago. Nothing this week. No cramps no spotting no bleeding nothing. Nurse.said based on my history and hcg not rising as much as they had hoped followed by the huge drop they str pretty positive with the outcome. Told me to prepare for the inevitable miscarriage. This time 5w+ 2d. I follow up with doctor is 2 weeks.
