Ohhhh Cath and Dani. So sorry today is a rough day again!
Cath, I just wanted to say hun, that you should talk over all the options with your doctor in depth and do lots of research before making a decision if you have to be medically treated for the ectopic. I know it sounds strange, and I mean it with love and support, but I will really keep my fingers crossed that your bleeding starting again is a good sign that it can happen naturally because the other options are all difficult.
But just FYI, my doctor in the EPU said they almost never just remove the ectopic from the tube and stitch the tube back up anymore because that has a really high rate of subsequent ectopics (due to scar tissue) and if you ovulate mostly from that ovary, your chances of repeat ectopics is a major concern. That is why, when they were prepping me for surgery (before they got my bloodwork back and realized I would mc naturally) they told me they would have to remove the entire tube. I know the MTX shot is awful, and so is the prospect of losing a whole tube, but I would just say really explore your options with your doctor before making a decision cause you want to choose the thing that gives you the best chance of getting pregnant again in the future!
Major hugs to you sweetheart!
