8 days late BFN

so I’m 8 days late on my period and my husband and I had sex on July 24 which was the day before i ovulated or the day of. We used the pull out method (as always) and my period is now late.

All tests have come back negative and I’m just so confused. I’ve been having cramping but higher up than period cramping as well as what feels like the stretching pain you get in early pregnancy (I’ve been pregnant 3 times, one miscarriage) but even with my miscarriage i got a positive days before my period was due. I’ve also had diarrhea cramping which i normally have when i get my period.

I’m just freaking out because it doesn’t feel like my period is coming and we are not actively trying. Also I haven’t been stressed or haven’t had any new changes.

Has this happened to anyone else and they ended up not being pregnant??

Or if you did end up being pregnant Please share as well!!
