UPDATE: I'm scared I may be pregnant

Hey girls ! I'm on cycle day 84, my last period was September 16th and I have not of course gotten my period. Many of you read my first post I believe it was 2 days ago. And well I went to the clinic today and received a negative. I have always had irregular periods but for the last months before September i have been regular. My symptoms include; vaginal discharge, nipples changed in size and darker, bumps around my nipples, swollen breasts in the morning, white spots on my nipples, i gained 13 pounds and i pee alot as well as eat alot and i got heartburn once this week. Also, i'm either always tired or very lazy. Yet my test at the clinic was negative 🤔 what is wrong with me ??? They told me to go back in 2 weeks to get blood work
