Am I pregnant

So I'll keep this short and sweet,
I just wanna know if anyone's had a very similar symptoms, and how it went for them, and if they came out pregnant or not, and I just need some adivce❤️
I'm 7 days late on my period, I took a pregnancy test 3 days ago and it came back negative, but it could have been too early to tell,
It's not that prominent but I've been having a sweet tooth recently
Ive been going gym and eating less meat, so I have no idea if that could be a reason for my period to be late
I've been bloated the past few days 
But I haven't had any cramps in my tummy, thighs, or had any spotting
I usually get cramps in my thighs and back if I'm due
I've been unusually hormonal and cranky but I guess it could be because I'm late,
Ive been late by two / three days in the past but not usually more than that
So a week or two ago I was peeing a lot, and it was stinging, so I concluded it was a UTI, I didn't go doctors because I had it before and it went away, which is bad, but could that also be a sign of pregnancy, I'm peeing a normal now, but sometimes I pee only a little bit at a time,
When it comes to contraception we have been using withdrawal and condoms equally, which obviously isn't that safe, I've been meaning to go get on the pill so if I'm not pregnant that's the first thing I'm doing.
I don't know:-(
I'm going to go doctors tomorrow
