Pregnancy question, please answer quickly in detail if possible?

im 17 and i thought i was pregnant like i had alot of symptoms no period, lil more discharge, stomach cramps, nausea, and really good smell senses. i took a test and it was negative. at like 1 in the morning. me and my boyfriend had with a condom but i don't know if there was leakage, im not sure we had like a month ago. i guess my question is along the lines of is it a low probability that taking the test before bed will show no pregnancy or should i try again when i wake up i heard it more accurate in the morning.. i don't know??
