Pregnant?

Jasmine
So.... I posted this before. Almost, questioning. B/c i really dont wanna keep buying test- im pretty sure thats where all my $ goes. (Though the last time i took a test was like the 2nd week AF hadnt showed)
Okay so... My last period was in Feb. i thought no big deal if it was late a week or two cause that does happen but its now a month- a week late. 
My boobs randomly get sore and i only notice when im not running around doing stuff. 
I feel this pressure- idk why- like in that area. 
Smells are SO MUCH stronger. 
I get dizzy/ having the feeling ima be sick. 
Im EXTREMELY moody. 
And im always tired- i never use to be easily as tired ( even when AF decided to show) 
And ik ive never really have symptoms when my AF was suppose to come, but AF still hasnt shown her face and she usually does by now. I know i have more symotoms those are just the ones that bother me. 
My SO seems to think i am prego and so does 3 other friends.... My SO seemed to convince himself through a friend who said this 
That seemed to make him even more sure.... Idk why. But that isnt the 1st i heard about dreams like that. 
And ive been having those types of dreams. -its weird so ima leave that alone. 
But yeah. 
So should i buy a few more test or just go get a blood test? 
And i called asking about blood test its around 120$ to get one, i cant afford that. -.- but yeah.... Help?
