Hcg levels

Glenda • I have a beautiful son name Deklan who is one , and now pregnant with baby number two :)
When I was pregnant with my son I knew before I missed a period and sure enough pregnancy test came out positive..I had blood work done at 3 weeks pregnant and they were at 17 so just enough to say I was pregnant. Had a perfect pregnancy no sickness at all, no cravings , I was all belly, and had my son may 13th 2015..
I am now pregnant with baby number two and once again I knew before missed period and all 4 pregnancy test were positive.i am sick all day every day nothing helps, all I want is sweets lol , had blood work once again at 3 weeks to just confirm.. And my levels where at 447!! I find that pretty high for being only 3 weeks pregnant I am now almost 7 weeks.
