New to ether and have a question

Hey yall. Friday morning I used blockchain to purchase $150 dollars of ethereum. Today it says it’s still pending but says it’s only worth 124.64. Why is this? If it’s pending why is it reducing in the amount of money? Is it usual to take this long to not be in my account and just say pending? I don’t see an option to speed up or give more money to the miners so I can have it in my account. I was hoping it would be pretty seamless like my experiences with bc and bc cash.
