Uh-oh

Now I'm a tad worried. My betas have been dropping beautifully every week -- until this week. They went from 58 to 34. That's not even a 50% drop. I know it's good that it's still dropping, but I'm worried that it's going to start to plateau. I know I shouldn't compare to last time, because they are completely different scenarios, BUT...last time they dropped well until it got to 20, and then it stayed at 20 for 3 weeks and I ended up getting another methotrexate shot and eventually a hysteroscopy to finally remove all the tissue. I *really* hope I'm not going to need surgery after all this anyway. Only time will tell...
