Can someone help me?

I am currently 14 days late on my period, me and my boyfriend have been having unprotected sex for a long time, my periods are irregular but usually I get spotting and some cramping around this time and usually that’s how I know it’s about to come in about a week or two and I’ve never been wrong about it. I took a test about 1-2 weeks ago and it said negative but I don’t know if I tested too early. I want to take another one because I’m hoping for a positive but I just wanted to see what others who have more experience have to say.

Here are some of my symptoms

- moodiness

- more tired

- My boobs are bigger and more sore than usual

- my stomach is out more and a little tighter but I’m not having any signs of cramping

- lower back pain

- nausea

- cravings for pizza even though I’m tired of it.

I’ve never been pregnant before and just don’t know how to tell if I am or not.
