Feeling confused

Samantha

No B.C. for 5 years or condoms. Today is going on three days on no AF. I took a test this morning and it was negative. I’ve tracked my period for a year and it’s never late. Always in the morning always on the day or a little early if I had sex... I know it’s possible to miss your period because of stress it happened to me two years ago when my fiancé passed away from cancer. And was missing for two months. But since then I haven’t had the problem. I lost my job in November but it’s not the same stress from losing a lover. My period I get light cramps before and on the first and second day I’m extremely heavy and cramps are severe.. past 4 days I thought my period was going to come but just weird slight cramps boobs alittle sensitive.. but I’m showing no signs of blood at all...

ladies how long should I wait to test again...

seeing a negative was pretty disappointing. I’m 23 being pregnant wouldn’t be the worst thing that happened to me. Waiting to know if I am or not or if something else is wrong is what’s killing me
