When i was worried about my levels during my mc i came across a lot of information on HCG levels during pregnacy so i hope the following help you out. Basically untill your levels hit 2000ish not much can been seen by ultra sound. And your levels are rising which is alwaya a good sign. Tyr not to stress to much
Guideline to hCG levels during pregnancy:
hCG levels in weeks from LMP (gestational age)* :
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
Non-pregnant females: <5.0 mIU/ml
Week 5 - Gestational Age (Fetal age 3 weeks)
Development
The gestational sac is often the first thing that most transvaginal ultrasounds can detect at about 5 weeks. This is seen before a recognizable embryo can be seen. Within this week, at about week 5 ½ to the beginning of the 6th week, a yolk sac can be seen inside the gestational sac. The yolk sac will be the earliest source of nutrients for the developing fetus.
Hormones
Human chorionic gonadotropin (hCG) levels can have quite a bit of variance at this point. Anything from 18 - 7,340 mIU/ml is considered normal at 5 weeks. Once the levels have reached at least 2000, some type of development is expected to be seen in the uterus using high resolution vaginal ultrasound. If using a transabdominal ultrasound, some type of development should be seen when the hCG level has reached 3600 mIU/ml. Although development may be seen earlier, these levels provide a guide of when something is expected to be seen.
