Late period but BFN

Hello Ladies!

As the title says, I’m now 7 days late today but I’ve only had BFN’s. My last was yesterday. I have never been more than a day late before. Has anyone else experienced this?

In the run up to when my period was due I had full cramps which was pretty normal, but the cramps have continued and I still have them now.

How late would you leave it before speaking to a Doctor?

Thanks xo
