I think it is possible. If you can't stand the wait, test anyway because you could still get a positive result before you miss your period. But, waiting is best. Every pregnancy is different (I've been told, since I've only had one) and so, you may experience different symptoms. I have an older friend who told me a long time ago, she didn't even miss her period yet but knew she was pregnant because she was so sick to her stomach. Sometimes, it happens and we just know. Other times, we don't have any symptoms until much, much later on. I hope whatever news you get, it will make you happy. Good luck!
