I feel pregnant!

I’m about 8 days late and I took a test the day before yesterday. They looked negative except one I took had a faint pink link. Tomorrow will be 9 days late. I’ve had cramping for the past few days off and on BUT no bleeding what so ever. I’m having some weird tightening feeling in my vagina area and lower abdomen. I know someone who didn’t even get a positive pregnancy test until she was almost two weeks past her missed period.

Anyone else go through this?? Negative tests and then ended up getting positives?!
