My last period was sept. 26 and I haven't had one since. All the test I take say negative and I had a blood test done in october. My periods are normally regular. I also have the symptoms of being pregnant like swollen breast, headache's, tired all the time no matter how much sleep I get, a little weight gain, To top that off I already have four kids so I know the feeling you have when you are pregnant. The samething happened with my last baby I didn't have a period for two month's and all the test where negative and then finally it showed up positive after two and a half month's. I'm going crazy trying to figure this out I know the feeling and I have it any help would be nice thanks.
