Confused HGC

nallsl

I had a blood test and urine test to confirm my pregnancy yesterday. My doctor wants me to go back tomorrow to do another blood test to check the HGC levels again. I think it's to see if the levels are increasing which means things are going as expected? 

Also, since I only had 1 cycle back in March, we are uncertain about the conception date. My doctor said I was "a couple of weeks" according to the blood test. If that is correct, then what would my approximate conception date be? I'm curious as to what my due date will potentially be. 

 I know that no one will have an exact answer, but some suggestions or guesses will be nice. Thank you!

Betas can't narrow down when you conceived or what your due date is. they'll need to do a dating ultrasound for that.

There is a WIDE range of normal when it comes to hcg. If you fall inside or outside these ranges, that's normal.

Weeks from LMP (Last Missed Period	Amount of hCG in mIU/ml or IU/l
3 weeks	0 to 5
4 weeks	5 to 426
5 weeks	18 to 7,340
6 weeks	1,080 to 56,500
7 to 8 weeks	7,650 to 229,000
9 to 12 weeks	25,700 to 288,000
13 to 16 weeks	3,300 to 253,000
17 to 24 weeks (second trimester)	4,060 to 165,400
25 weeks to term (third trimester)	3,640 to 117,000
After several days postpartum	nonpregnant levels (<5)

 
If your readings fall outside these ranges, don't worry: It's still quite likely that everything's fine. (Your due date might just be off.) As long as your pregnancy is progressing normally, you don't have to obsess about these numbers (especially once you've past the first trimester), but if you are concerned, talk with your practitioner about your results.
