So my first HCG levels was 88.60 2 days later it was 333.4 the next day I was having some cramping so I went into the er where they told me my levels were 240. Keep in mind all blood work was done at 3 different labs. Dr told me I was likely miscarrying. 2 days later I wake up to realize my boobs are twice as sore as they were and my symptoms have only increased instead of decreasing. With all my previous losses I bled immediately and passed tissue and lost symptoms the day after. My levels are not so high it's going to take weeks for them to go all the way down. Does anyone have any idea or similar situation?

First test was today, they told me I was miscarrying 2 days ago. This bottom test was my first test so why is todays test darker if my levels are supposed to be going down?
