Hcg level


I just went in for my 2nd reading and I got the results from my first I was supposed to have my period 3/30 this blood test was taken 4/2 are my levels normal for that date range or are they higher/lower than normal?

I measured 605.0 miu/ml

2 days after missed period I believe according to my sex chart I would have conceived either the 15th or 17th of March.. Not sure how many weeks that would be my previous period started March 1st and the next one was due March 30th (29 day cycle?)

Please advise... Thanks

I had a miscarriage in October so I'm super worried
