Girls, hello, there's a delay of 10 days. All three tests show a weak second line (the tests were bought in different pharmacies). At the same time, I started feeling pain in my lower abdomen, but it sometimes hurts, and menstruation hasn't come yet. Can you tell me if there is a chance of pregnancy or did the test misread before menstruation?
