Mine was a bit different though, I woke up Tuesday with pain in my shoulder and knew something was not right. I had a follow up blood test then went up to the ward were I had been - I finally got admitted (after one nurse tried to send me home) and was sent for the ultrasound. Before they started my bloods came back showing my hcg levels had doubled. I ended up having emergency surgery to remove the tube.
Once the tube was removed - from my understanding - my levels dropped down to 0. I think it was almost 2 months till I got my period again. But I have fertility issues (pcos) so my cycles are all over the shop
