I took a pregnancy test it was negative but everyone says that I took it to soon

Hmm, that is very weird i have never even heard of that happening. But to answer your question when i was at my doctors appointment when i found out i was pregnant they told me that it takes a couple minutes for the sperm to actually die when exposed to oxygen which i thought was wrong because i always thought once it hit oxygen it immediatly died when exposed unless my doctor was wrong. i would defintely wait maybe a few more days or maybe another week to take another test and see if you still havent gotten your period i would def go to the doctors and have them do a blood test because its 100% accurate. Im not really having similar problems but i had put up a post about my period and no one has helped it out idk if you would know or anything but 3-4 months after i gave birth to my son i had my period and i havent had it since the end of January so thats what 3 months and everything that ive looked up online has told me thyroid problems and everything but i talked to my doctor and he told me if i start taking my birth control again it might start it back up and it didnt i stopped taking it because i thought that was what was making me bleed for weeks upon weeks and it was very heavy. And ive taken about 6 pregnancy tests throughout these last 3 months and there all neg so i have no idea whats going on. Ive been doing the Insanity work out but ive only been doing that for two weeks now so it cant be from excessive exercise. I hope you find out whats going on though. Good luck! Im here to answer any questions you have :)
