5 days late. Negative pregnancy tests

Ana

I’ve taken at least 4 negative pregnancy tests but still haven’t got my period. I know I should wait another week to test if I still don’t get my period but this anticipation is killing me!

My nipples have gotten bigger and darker. I read that’s an early sign of pregnancy... but I don’t feel nauseous or any other other symptoms. I’ll occasionally get very light cramps. Any thoughts??
