So I was supposed to start my period on Friday and end Tuesday, I didn't start, had no spotting or anything. My husband and I had sex on my last ovulation day. I have been experiencing fatigue, I'll be fine one second and than the next extremely tired and fatigued. I also don't feel like my normal self. I keep having ups and downs in my mood, I feel neutral, than great and than depressed, I also feel like I've been peeing on stop, like every hour or two. I've taken three tests and they all were negative but I took those during the week my period should have been happening. Should I wait until next week to test? Do I go get a blood test? What should I do?
