Any ideas/experiences would be welcome. My cycle is usually 26 days and my AF is now 3 days late. I tested yesterday and it was a bfn. I am just starting to worry myself sick now that I may have an ectopic pregnancy, but how long would it take before I had any symptoms? We had DS 18 months ago after 2 failed cycles of IVF and being told we would never conceive naturally. We did. I have only one tube and in the words of the doctor, it's "mangled". None of them could see how I had managed to get pregnant when I was scanned at 6 weeks. Anyway, should I test again? Should I wait another week or two to see if AF is just playing tricks on me? Should I wait to see if I develop symptoms of an ectopic pregnancy? I am terrified that I could lose my other tube. I know I'm probably overthinking things but what to do?!
