Help??? False negative ?

Has anyone had a false negative pregnancy test with all the symptoms of pregnancy?

It’s 3 days until my expected period and I’m experiencing all the same symptoms as when I was pregnant with my daughter. I have tested 4 days & 3 days before predicted period (yesterday and today) and both were negative, with the slightest hint of a second line though I really had to angle it etc to see it, so I’m thinking it’s an indent… With my daughter I had the most obvious positive pregnancy test, though I tested 2 days after my missed period… it could be PMS, but I’m hoping not. Is there still a possibility of being pregnant? Or unlikely?

My symptoms includes-

Extreme fatigue/exhaustion.

Insomnia.

Very sore/achy & leaking breasts, (I’m still breastfeeding my daughter but they’re leaking which they haven’t done since she was a couple months old).

Headaches.

Nose bleeds.

Cold/flu symptoms (achy body, runny nose)

Sensitive smell (I have sinus issues so usually can’t smell anything but the last 2 days I’ve felt nauseous everytime I change my babes nappy or smell cigarette)

Constantly thirsty.

Back ache and tingly/pulling sensation in the left side of my lower abdomen. Mild cramping.
