Started spotting on 30th September, which I assumed was my period as I was due on 3rd October. Took a pregnancy test on the Sunday as I had symptoms and it was positive. I was still spotting. I had an early scan at 4w2d (estimated) and was diagnosed with a pregnancy of unknown location due to them not being able to see anything. I continued spotting and then had blood tests which shown my HCG levels practically doubled from 54 (8th oct) to 104 (10th oct) I then started bleeding heavier and passing clots and tissue like substance. I had another blood test on 14th Oct where the levels shown 199.
