Okay, so I'm a little confused. I'm very late on getting my period and I'm very worried that I might be pregnant. This is pretty improbable though, because not only did my boyfriend and I use a condom every time and they did not break, he also has never cum inside of me. My last period, however, was September 27-29 and I have not bled at all since then. According to my little period calculator app on my phone, I was fertile the 9-13th and ovulated on the 14th... we had sex the 9th, 14th, and 15th. I have always been pretty regular-never more than a day or two late. My period SHOULD have started October 31st and ended on the 5th, but it is already the 14th and nothing has happened. I've taken two pregnancy tests. One on the 8th and one on the 12th. Both were negative. Besides being unusually tired, I dont really have any common pregnancy symptoms. I'm 18 years old, 5'4, 130 lbs, healthy, and pretty active. I was thinking maybe my period could be late due to stress but I'm not really stressed any more than usual. Its so weird. I'm almost two weeks late! I really hope I'm not pregnant. I feel like maybe I'm not since a pregnancy test should be able to detect it by now and I'm not throwing up or anything. I'd appreciate it if y'all could help me understand what is going on with my body!?
