Is it possible for beta-hCG to come back negative throughout pregnancy?

There is no way that in a properly proceeding pregnancy the concentration of the hormone beta-hCG in the blood will not increase.

To @meia: Pharmacists do not interpret ultrasound results. Ask your doctor about this.

And are you able to write what was shown on the lower ultrasound picture? At the top I know that this endometrium, unfortunately at the bottom I'm not sure. Please help, although I know that you are not a doctor

To @mieia: You can rule out pregnancy.

And in case of using any medications? I did the beta after 12.33, 44 days after intercourse. If the pregnancy was really detected? Do 3 withdrawal bleeding on time exclude or can it also happen?

whether a blood test is performed more than two months after intercourse, the result

To @Ewka: In my opinion, there is no need to repeat the beta-hCG and ultrasound examination.

Thank you, I forgot to add that a month and 1 week after intercourse or a total of 5 weeks after intercourse I was at the gynecologist I also did not notice anything, I think I can be billionth sure, whether in your opinion should repeat the blood and ultrasound yet

To @Ewka: If the results of both tests indicated that there was no pregnancy, then pregnancy can be ruled out.

I did two betas in two different labs, one 26 days after and the second month after ? I can be sure if it should be repeated?

To @Ewka: If the test was performed only once, it can be repeated to ensure that the result did not come out false negative (this very rarely happens) due to a measurement error. If the negative result was not false, then pregnancy can be excluded.

So if a month after intercourse I have a negative beta, it means that there is no pregnancy? Since you say that there are no such cases
