Hi everyone - this is my first pregnancy, and still very overwhelmed by everyhting associated with early pregnancy!!

I am 5wks and 3 days today and just a tad concerned about my HCG levels.

First blood test was last Tuesday 17/3. The result came back a little lower than expected, hence the 2nd blood test on 20/3. Apparently my levels have increased by two thirds, but not doubled??

I am now having a 3rd blood test on 27/3 to test levels again.......

Any opinions on whether this sounds safe/normal? Should I be getting exact HCG numbers?

Just starting to worry a little....
