HELP!!!

Hello! Im very new to this app and im honestly just looking around for advice or an idea of whats going on...

i (f17) have sex w my boyfriend unprotected (you can see when based off the little pink hearts) and im now 8 days late. We make sure we dont make any close calls so he doesnt finish inside. I took a test when i was two days late and six days late and they BOTH came out negative. Ive honestly had a tough three weeks and it could be stress but it also feels like something more. And yes i understand that stress does have a part in this but it doesnt feel THAT bad, ya know? Idk... I will occasionally feel some dull pain that feels like cramps but then they go away as soon as it starts. Nothing else has been hurting, boobs havent changed, im not bloated or nauseous, my discharge has been on and off switching from clear to white. Ive mentioned BC to my mom but she freaked out and said no. I feel like something is wrong and idk how to fix it.

My diet mostly consists of dinner and lunch every other day. I drink water and sometimes take a vitamin just so i have something in my system but i tend to forget to take them daily. I used to vape but i quit early last year and i dont really do anything else.

If you all have an idea of what this could be please tell me! Or if you have any ideas on how to start my period then tell me that too (i tried the parsley ginger lemon tea thing it hasnt worked)

Ik this is a lot to absorb but your response would mean a whole lot! :)
