Changing hCG levels

By Anonymous September 23, 2015 - 6:01am

Slightly confused. I read on here that dry humping with clothes cannot lead to pregnancy.

I did HPTs and 2 blood tests just in case...
The first time my beta hCG was 0.5 (which was about 8 weeks after the event)
When I went for a second blood test, it was 1.2 (which was around 15 weeks after the event)
So what is the cause of rising hCG? Am I not pregnant? My period was a little late but it came the following day after I went for the blood test. Could the hCG rise slightly if my period were about to start?

Hello Anonymous,

Welcome to EmpowHER. Thank you for asking such an interesting question.

Normally, hCG is a hormone that is only produced during pregnancy. A qualitative hCG test detects if hCG is present in the blood. A quantitative hCG test or beta hCG, which you had, measures the amount of hCG actually present in the blood.

An hCG level of less than 5mIU/ml is considered negative for pregnancy, and anything above 25mIU/ml is considered positive for pregnancy.

A low hCG level reported on both tests and getting your period confirmed that you are not pregnant.

hCG tests are capable of detecting very low concentrations of the hormone. There are three reasons for a positive hCG test in the absence of pregnancy.

1) Biochemical pregnancy. A biochemical pregnancy occurs when a woman becomes pregnant yet has a spontaneous loss of the fetus before she even knew she was pregnant. If hCG testing occurs before all of the hCG has been metabolized out of the body then hCG can be detected by a lab test. This situation is not uncommon.

2) Pituitary hCG. Although the placenta normally produces hCG during pregnancy, it can be made by the pituitary gland. Non-pregnant women with pituitary hCG usually have low concentrations of hCG present in the blood and urine. Importantly, concentrations of hCG produced by the pituitary gland don’t show the rapid increases that occur during pregnancy.

3) Interfering antibodies. Some women have antibodies in their blood that can interfere with hCG tests and cause a positive or elevated result in the absence of hCG.

Anonymous, please consider taking with your gynecologist or the healthcare provider who did the blood tests.

Hi Maryann
I did ask her and she said that anything under 5 is a negative and that HCG levels can change from day to day. I just wanted to make sure whether this information was correct.

She also did an ultra scan and it showed nothing BUT said both my ovaries were polycystic which explains my late period. I just came on a few days ago but i was wondering if all this could effect HCG levels from rising (its probably best to note that i am taking Microgynon 30 to make my period regular)

Should i be worried after this encounter. I heard that dry humping with clothes on cannot cause a pregnancy? I've not had any sexual encounter after this event

Hello Anonymous,

Dry humping or making out with clothes on does not lead to pregnancy. You have nothing to worry about.

Any further concerns you may have regarding hCG levels and the diagnosis of polycystic ovaries should be discussed with your doctor.

Will do ..

But I guess I just needed to know whether small amounts of hcG is normal even if your not pregnant

Hello Anonymous,

Only in the above mentioned cases. Normally, you should not have any hCG present in your blood.
