do you think i might be pregnant?

So my boyfriend and I have kinda been trying for a baby. I'm exactly one week late on my period and a few days ago my boobs started hurting really bad. It's like a burning situation deep in the middle of both of them and it actually had me in tears one day because the pain was so bad. They also feel heavy and even look bigger. The only way I can keep them from hurting like that is to wear a bra to bed and it's usually the other way around. I have never felt that kind of pain in my boobs. I have always had a small chest so I can definitely notice a difference in size almost immediately. Also lately I have been getting really tired earlier in the day. I usually struggle to sleep at night and don't get to sleep until 4-6am. I have been this way for years. Because of this I took on midnight shift at work and it got so bad that I had actually fallen asleep which I NEVER do! I have been a bit bloated as well. I have also been a bit emotional but I have also been going through some tough things in my life so I'm not sure what it could be from. I'm so nervous to take a test because I want it to be positive and if it isn't it's going to crush me because for a long time I thought I couldn't have kids. I'm also having dull cramps in my lower stomach. They feel sort of like period cramps but much less intense (I have extremely painful period cramps when I have my period). I also have a bladder infection so I'm not sure if the frequent trips to the bathroom are another sign or if it's because of the infection. (Im 24 years old)  i don't know why but I just have this weird feeling that I am. I have had "scares" in the past but have never had symptoms like this.
