The occurrence of 3 withdrawal bleedings excludes pregnancy. We wrote about situations that may affect obtaining a false positive result when testing the beta-hCG level in the opinion: https://www.gdziepolek.pl/opinie-i-pytania/85911/jakie-czynniki-moga-zaburzac-wynik-beta-hcg-i-jak-przygotowac-sie-do-badania False negative results can be obtained after e.g. too early test. The determination after 36 and 45 days after intercourse is correct and reliable. If a negative result is obtained, it can be concluded that there is no pregnancy. I encourage you to read our study on pregnancy tests: https://www.gdziepolek.pl/artykuly/test-ciazowy-jaki-wybrac-i-kiedy-zrobic
