Still no answers

So today I went for the ultrasound, and the dr was unable for find anything. Here I thought I would be getting some answers today but no, I left still not knowing whats going on. He looked in my tubes and my cervix so he doesn't think its ectopic, but he was unable to clearly see anything. I have to wait for my numbers today and go back tomorrow, and then we might set up a d&c to see if that helps. If my numbers don't go down after the d&c then I will have to take a methotrexate injection in case it's an ectopic pg. I really don't want to do that so I am hoping the d&c will be enough.
