Subchorionichematoma

Anyone had experience with this. Iv just done first round of ivf after 8 years of trying and miscarriages. To my joy it implanted then the bleeding came and pain. I was told in sime cases it can be normal just wait for your 7week scan then i had 2 more episodes so i just booked a private scan wich said i was measuring around 5w6d baby and yolk no hb said was to early. But i did have a subchorionichematoma that was clotting up. Oh i had also 3 hcg bloods taken leading to this wich was doubling nicely. But take me to yesterdaythe day after the scan i had another bleed but this time so much pain all in my lower right side. I went to hospital was given codeine and bloods taken wich shown no doubling my last bloods was monday at 8701 then friday yesterday was only 14000. So im tikd more likely the pregnancy insnt progressing and to have more bloods tomorrow. Im heartbroken as i thought this was finally it. And im so confused as to what it is with me and my partner as i had no problem with my previous partner having my beautiful children. Then i met my now partner and we have never gotten to a heart beat stage.
