Did anyone else feel this and get bfp?

I've been having cramping literally since 5dpo it's been 7 days almost 8 and it hasn't stopped. It's in my back now and all over where my uterous is. I'm so bloated I can't even do up my jeans and when I tried to do my usually work out today I was so dizzy I only made it a third of the way through it. And the last symptom I've had is I'm exhausted. Today I slept for 15 hours and then I felt like I could stay awake. I am so tired all the time. 😪

This is not normal for af.
