Another am I pregnant post 😒

I HATE these posts. So I am aware that I sound annoying to bare with me, I am going to get a pregnancy test as soon as I get off work. 
I took the plan B about 2 weeks ago within 72 hours because we had a condom break. I got off of birth control and I've been looking into an IUD because I have bad side affects from every hormonal birth control I try, from cystic acne to throwing up and bleeding nonstop. 
I don't think it worked?  
I am not due for a period for a while. 
After I took the plan b my boobs were killing me and I figured you know, it was due to the massive dose of hormones I took. They've been hurting nonstop for 2 weeks. 
Yesterday they felt a little better I thought yes it's over back to normal I go. 
No. 
Today, I woke up with massive boobs. Like I kept looking at them because I couldn't understand why they felt different.  they are fuller on the sides and are super heavy. and I couldn't even get my hips into the same pants I've been wearing for years, it's not even weight gain it's like my hips just got wider. 
I know that usually women don't get pregnach symptoms until week 6 and the only way to know is taking a test, but is it possible that I am already having these symptoms? We're these your symptoms super early on? And if I am I'm keeping the baby. I'll just be upset about it for a while. Also, I read that the plan B only stays in your system for like a day after you take it, so why would it still be affecting me?
Added: no I have not taken a test, check back in 9 hours for that lol. 
Took a test, not pregnant.
