Please read and tell me what you think...

Okay so I am 16dpo and my period is a week late today I tested this morning and it was negative but I’ve been having symptoms such as cramps and pinching and a washing machine feeling in my belly for maybe the last week. I have also been having thick jelly like sticky mucus and Ive got serious back ache and I’m exhausted all the time....also the bloat is very real. I also want to eat everything i see😅 I just don’t understand how AF can be a week late and I’m still testing negative... I’ve never ever been this late before, maybe a day but a whole week??? What’s going on? I hope I am pregnant🤞🏼
