Hi guys, im new to this kind of thing.. So be kind

Im looking for other peoples opinions on what this could be. So heres my story;

I went off the pill about a couple months ago. I have had 2 regular periods since then and i was meant to get my period on the 12th of January but it hasnt come. The weird thing is that i didnt have unprotected sex until the 20th, 21st, 22nd.. Although i did have sex with condoms. None appeared to have broken. Today is the 31st and i still havent got my period so im wondering if i could be pregnant?
I have experienced some of the symptoms of pregnancy but i dont know if its all in my head..

Food cravings
Fatigue
Morning sickness (although not necessarily in the morning)
Ive had a kind of metallic taste at the back of my tongue.. which was gross and weird.
Some things make me feel queezy suddenly.. like the taste of toothpaste etc.

I did take a pregnancy test which came back negative.. but that was only a few days after i had unprotected sex.

Do you think it was a false negative? or is it in my head..

Wanting a baby..
