Hello dr. richmond. i'm concerned that i may be pregnant. i'm 3 weeks late for my period but i've taken 2 home pregnancy tests that were both negative. i've noticed some early pregnancy symptoms but i'm worried that i could be making them up in my head. d

Not pregnant: There r a lot of things that can cause a delayed period but with 2 negative pregnancy tests it is highly unlikely that u r pregnant.Stress alone can cause this as can weight changes,diet, exercise, medications,and illnesses like thyroid disease, diabetes/insulin resistance,PCOS,adrenal disorders, and pituitary problems.See your PCP or gynecologist for a full history, exam,and tests to know 4 sure.
