No result but symptoms?!

Okay so I need some advice please, I was late on my period and then had dark pinkish blood in my knickers, I’ve had pregnancy symptoms such as stomach cramps (very bad)!, nausea, feeling sick, headaches, and even my eye twitching, I would be over just a month pregnant but it’s showing on the test negative, I’ve done research about this but apparently some people go through this? :/ if anyone could please get back to me about this and let me know if I could be or not that would be amazing! I’m only young and I don’t really understand much of this

Thankyou Amber xx
