Pregnancy Info HOME

i had s_x a day or two before i was supposed to get m period, now its 15 days later and im always tired, my br___ts hurt and are swollen, i cant stop eating for anything, and i just have a feeling that i am. i was pregnate before but i miscarried. im 20 years old and i have irregular periods... but something just feels different, like the time when i was pregnate. i took a home test today and it came up negitive. but i just feel that it is wrong. i also didnt use it first thing in the morning, but i had been holding my urine for 6 hours. is there a way that the test is wrong, and that i am pregnate? does it sound to anyone else that i am? how long should i wait to repeat the test or should i even bother?
