Thank you so much for reply. Yes I have an ectopic on my left tube and was treated with methotrexate 2 weeks ago. The numbers have been falling. Not yet at zero. My mass was around 1.9 x 1.2 x 1.3 but I am in Uk they dont offer rescans if numbers are falling ok. So worried if the mass will stay there , I am thinking to go for scans privately after levels go to zero. I dont have any pain so far . Thanks for response it has helped. I am finding it such a slow process too and very draining experience. I hope yours disappear completely soon. Did your obgyn give you the clear to have sex even though the mass is there , I am worried about that too. They only told me to wait until HCG is zero .
