My husband and I are not planning on TTC until later this year but we haven't been preventing. I am wondering if I might be pregnant, if it be a medical issue to get checked out or if I am just irregular. I have pretty regular periods. This is the first time I have ever been late with no symptoms of starting. I am only 4 days late but for me that's late. The only sign even close to my period started on the day I was supposed to start and that was very mild cramping that has been on and off for the past four days. I have been warm but no fever, I have been lightheaded, have had dizzy spells, queasyness especially more towards the evening, headaches, tender & warm tummy and more tired than usual! Interesting enough I have no tender breasts or mood changes which is the FIRST thing that tells me my period is on the way. I took a test today and it said negative. I wonder if it is too soon for the pregnancy hormone to be detected or if something else may be going on. What do you think?
