important question!!!

Hi! My HCG levels are:
6/21- 25.3
6/23-59.6
6/26-260.1
This morning I woke up with bright red spotting. Now it's brown spotting....I have zero pain at all but I am high risk for ectopic because I had a tubal reversal. I called my doctor and I'm waiting on a call back but I am wondering if anyone has ever had this? 2 miscarries previously numbers never doubled. TIA!!!
