58 days late help post

So I’ve seen a couple posts about ladies being extra late and still having negative pregnancy tests . I have taken 6 tests in total with 2 being at the doctors . The 4 tests that were taken at home were all negative . I spaced them out and tried to ignore my ever late period . I finally went to the walk in and took a test , after 2 days I was told it was negative and that I had a UTI. During these times I felt bloated and a hunger that I couldn’t seem to satisfy . I had no symptoms other than back pain and a pinching feeling on my stomach . A week after my test at the walk in , I went to see a doctor at a different walk in and told him about my problem . He tested me again and came back to tell me I did not have a UTI and that I was indeed pregnant . I asked why I could not get a positive on the home tests or the other doctors and he said that it does happen to some woman , sometimes they need to try a couple different testing methods . I found this out at my cycle day 58 . Sorry for writing this without much detail I thought I would post it to help others
