Eptopic or too early?

Hi everyone, according to my last period i should be 7 weeks tomorrow, at 5+2 days i had a light bleed when i wiped only once and a niggling pain on my right side but not severe. I went to the EPU who did a blood test and the HCG came back at 715 because of the niggly pain they did an internal scan which 'they thought' they could see something next to my right ovary, but they wasn't sure at all. 2 days later i went for another blood test which came back at 626. I spotted with very light pink only when i wiped for a few days on and off. They suspected eptopic and was told that there was a corpeius cyst on my right ovary and something tiny next to that also, the sonographer never told me this she only said there maybe something next to my right ovary which i found very strange, so there both telling me different things. That evening i went up to the gynaecology ward as when i wiped there was blood again, they checked me out and told me to go and have my bloods done 2 days later. I went for my bloods done on the Saturday to which my levels were back up to 960, 2 days later they went up to 1600 and i had a scan to which it was the same sonographer, she was umming and arring and said she could maybe see a sound wave in my uterus but couldn't see my right ovary very well and was sure she could see something next to it last time, 2 days later i went to have my bloods done again which were at 2300. They then rang me and said they wanted to see me as 'they should be seeing something by now' what if its to early and my dates are wrong or i ovulated or implanted late?? Im getting white discharge now and again which i keep thinking is blood so i rush to the loo and its just full white discharge. Would i get this if it was eptopic? I'm so worried they are not 100% sure and will mis-diagnose me. Has anyone been through something similar so desperate for a happy ending :(
