Hey, my husband and I have been trying since we got married 20 months ago. My period was clockwork every month until we went to the doctor about not conceiving. We are now looking at IUI or IVF (find out on 31st). My periods have been messed up since our first doctor appointment in December. I am currently 4 days late but 2 pregnancy tests were negative. I am really trying to remain calm and stay stress free as I know my cycles will determine the starting date for treatment. My body must be secretly stressed tho and maybe affecting my period. Has anyone else experienced this? I was so convinced that I was naturally pregnant . I have never been this late before and just feel devastated now. I got clear blue digital tests so there was no misreading the test.
