pregnancy help?!

Ladies ! Those who have been pregnant or is pregnant! I've had constant cramps for te past three days, my period is late by a day and I feel the need to pee straight after I have already gone... (yes I have had unprotected sex recently) but I want to know what your cramps were like and what you felt like down there.. (sorry if it seems creepy or anything 😅) 
Thank you in advanced x
