What could a decrease in beta hCG mean?

To @Agaa:

The level of beta-hCG, which rises during pregnancy, may initially fluctuate in the event of a miscarriage and then begin to decline, which is a normal process if a miscarriage has occurred. If your gynaecologist has suggested that you will experience bleeding within 7 days, it may mean that a miscarriage is very likely. A recent beta-hCG value (455.06) indicates that the hormone is still present in the body, but whether the situation is finally clear depends on how the beta-hCG level behaves in the coming days.

Repeating the beta-hCG test after 48 hours makes sense, because usually, in the case of a normal pregnancy, the level of beta-hCG increases at a rate of about 50-70% within 48 hours. If, on the other hand, there has been a miscarriage, the level of beta-hCG will begin to drop, which can be seen as a result of such a test.

Severe pain in the lower abdomen, especially with such changes in beta-hCG levels, may indicate the beginning of a miscarriage or other problems, so it is worth monitoring the situation. If the pain gets worse or you experience other symptoms, such as heavy bleeding, it's a good idea to see your doctor to make sure everything is okay and there are no complications.

Good morning
In my case, the situation is as follows: 1.03 Beta 24.69 3.03 46.89 5.03 108.06 5.03 fever appeared, positive test for influenza B 11.03 beta 448.16 13.03 beta 455.06 The gynaecologist said that he would not see anything on the ultrasound anyway and said that within 7 days there would be abortifacient bleeding. Today there was a temporary engine pain in the lower abdomen Does it make sense to repeat the beta after 48 hours? Is everything already obvious . Of course, hope dies last Thank you for your answer
