Testing to early!!????

I have taken a pregnancy test for the last three days and they all come back negative:(. I'm supposed to start on Wednesday 9/24. I haven't gotten my usually cramps and everyone around me feels I'm pregnant. We are trying for baby #2! I feel defeat. But I also think it could be in my head. Just I just wait and see if I miss and just trust the test. I have also been doing them with the first pee. I need answers????
