Losing itttt

My period is currently 15 days late. Took a bunch of EPT, one came back with a faint positive line. I go into the doctor and take an EPT there, faint line again. HCG blood test, negative. But I’m having a lot of symptoms and have an ongoing migraine.

Anyone ever had this happen before? I feel like I’m losing it. My mom is convinced I’m pregnant and feels I should get a second opinion. I’m just tired of feeling crazy. 😩
