Strange cycle

My last cycle was Oct 24th, by all accounts normal, 5 days and done. I've been off oral contraceptive for 4 months (I turned into an hormonal mess with rage and decided it wasn't worth it.) On Nov 16th I started to spot for 10days. Since then I've experienced every early pregnancy symptom one could have. Multiple negative pregnancy tests and still no period. Has anyone had this experience? Is it possible my hormones are still off from the pill? -waiting to bleed
