During the first 12 weeks of pregnancy, the HCG numbers are not so important. After the numbers reach around 0-50mIU/mL, the urine pregnancy test becomes positive. Thereafter the numbers rise very fast. The actual numbers can show a wide variation amongst pregnant women in the first 12 weeks, but what remains constant is that the numbers keep doubling up. In most women the levels double up every 48 hours, but in some it may take about 3 and1/2 days. If this trend is seen chances of pregnancy carrying forward are high.
So, in your case, yes, it is a cause of concern. However, it’s too early in pregnancy to give a definitive answer. While you wait another week for a clearer picture consult your gynecologist to find why you had a miscarriage earlier. Generally first trimester abortions or abortions occurring in first three months are due to fetal abnormality, genetic causes, Rh blood group incompatibility and low progesterone hormone. Infection of the uterus, endometriosis, fibroids, etc are some other causes for early abortion. Some of these causes are pregnancy specific and may not recur, while others can. You need to consult your gynecologist and run some tests to rule out these causes. Eliminating these causes will increase the chances of full term pregnancy.
Thank for the response. I had another HCG test four days after the last one (216), the numbers did go up, but only to 333. I have an ultrasound on Thursday. Im not optimistic.
