Hallow Dear,
hCG is a hormone which is produced by chorionic tissue during
pregnancy. The chorionic tissue ultimately forms the placenta. Therefore throughout the pregnancy, hCG levels go on increasing. In fact this high titre of hCG levels cause the
pregnancy tests positive.
For your ready reference, I am quoting herewith the levels of hCG during different stages of pregnancy:
3 weeks LMP: 5 – 50 mIU/ml
4 weeks LMP: 5 – 426 mIU/ml
5 weeks LMP: 18 – 7,340 mIU/ml
6 weeks LMP: 1,080 – 56,500 mIU/ml
7 – 8 weeks LMP: 7, 650 – 229,000 mIU/ml
9 – 12 weeks LMP: 25,700 – 288,000 mIU/ml
13 – 16 weeks LMP: 13,300 – 254,000 mIU/ml
17 – 24 weeks LMP: 4,060 – 165,400 mIU/ml
25 – 40 weeks LMP: 3,640 – 117,000 mIU/ml
I would say that at 7 weeks the titre of hCG 32000 mIU/ml or 42500 mIU/ml are within normal limits. The baby is growing normally and you need not be worried about.
Hope this helps you.
