Does 7mm uterine lining affect pregnancy?

Question
Hi doctor,
I took the test for 3 consecutive days and found 1 dark line and 1 faint line, I went for transabdominal ultrasound, my endometrium is 12mm (no pregnancy) and the HCG test is 158.01 . The doctor concluded that she was pregnant. Then I went back to the ultrasound probe: the endometrium is 7mm (no pregnancy) and the HCG test is 1564.36, which concludes that the pregnancy is developing. The endometrium decreased from 12mm to 7mm, but the HCG increased. Doctor let me ask when the 7mm uterine lining is pregnant? Thank you doctor.

Hello,
To the question: "Does 7mm uterine lining affect pregnancy?" The doctor would like to answer as follows:
HCG stands for Human Chorionic Gonadotropin, which is a hormone secreted from cells that form in the placenta after an egg is fertilized and implanted. The beta HCG test is a test that checks the level of beta HCG in the blood or urine. By accurately measuring beta HCG levels with high sensitivity, it is possible to determine conception from the 8th to 9th day after ovulation. Thereafter, beta HCG levels rose rapidly, doubling in just 1.4 to 2 days. HCG will reach its highest level at 60 to 70 days and gradually decrease to its lowest level, stabilizing around 100 to 130 days.
Blood beta HCG levels according to gestational age are usually as follows:
3 weeks: 5 - 50 mIU/mL 4 weeks: 5 - 426 mIU/mL 5 weeks: 18 - 7,340 mIU/mL 6 weeks: 1,080 - 56,500 mIU/ mL So with your HCG level, your pregnancy is equivalent to about 6 weeks, with this gestational age through transvaginal ultrasound, the gestational sac is clearly visible in the uterus, but the endometrium is 7mm and the cyst is not visible. pregnant. Most likely, you have an ectopic pregnancy, also known as an ectopic pregnancy. You need a follow-up exam, ultrasound, and tests to confirm the diagnosis, then treatment. An ectopic pregnancy is a condition in which the fetus does not implant in the uterus, but lies outside, which can burst and bleed, affecting health.
If you still have questions about an ectopic pregnancy, you can go to a hospital under Vinmec Health System to check for an ectopic pregnancy. Thank you for trusting and sending questions to Vinmec. Wishing you lots of health.
Best regards!
