Need some real life stories

Has anyone at all gone through getting negative tests to find out they were actually pregnant?

I have been having symptoms since mid December. Like every symptom, sickness, cramping, nose bleeds, foggy brain, headaches, you name it. The main one being I haven’t had a period for 2 months now. I was never trying for a baby so I’m not stressed or over thinking anything, apart from now. I keep getting negative tests and I’ve read on the internet about people who was getting negatives up until like 5 months or more. I will be going to the doctor if this next period that’s due doesn’t come (no signs at all) but, just wanted to know if anyone here has an experience like it.

Thanks
