Worst day of my life😞

Im 5-6 weeks pregnant (well i was.) Ive been spotting for 10 days now (bleeding a few days within those 10 days but not heavy) i went to the hospital at 4 days and my hcg tested at 75... well spotting then 6 days into my spotting i went back for a retest and my hcgs went up to 161! I was so happy! Well i was bleeding again... a little bit more that day so 2 days later i went again and they only went up to 220. I worried a little but pushed it to the back of my head thinking it was normal and okay. Well today the bleeding got bad. Clots and ive had alot of back pain lately but not severe cramps.. i went to the hospital again and i was told my hcg levels were trending down and my heart broke. I wish my story could be happy and end good like alot on here but i guess i was the unlucky one and my baby wasent meant to be😞 we are going to try again but the emotional pain has me hurt, confused and thinking “why me?!”😢😔😔😔
