My period is 13 days late but pregnancy tests are saying negative. I'm normally pretty regular and being 13days late has never happened to me before. Me and my partner have been trying to conceive for some time and have been having tests for infertility. All my tests have come back normal including bloods, ultrasound, internal scan so I am quite confident that there are no medical issues I should be concerned about. Has anyone else ever experienced this? I hear of people taking pregnancy tests and them showing negative incorrectly but I would certainly expect for something to show by now if I was pregnant. Has anyone ever had a similar experience? I'm worrying that something has gone wrong but then think well my tests would have shown something but then I'm not due another gyne appointment for 2months so don't have anyone with experience of these things that I could talk to.
