1 week late

I'm one week late on my period, but I'm nervous to take a pregnancy test. I have taken them before and always come up negative. The problem with being irregular is that I am never quite sure what's going on in my body. I just have to read the signs.

My tummy is a little crampy but the rest of my body shows signs that I should be getting my period soon. One sign is that I cant have my knees together while I sleep or otherwise I'm in constant physical pain. Either my boyfriend lays his leg between mine or I have a pillow between them. I'm extremely hungry and thirsty all the time and I always feel tired. These last two symptoms are kinda new, especially the thirst. My back and leg muscles have been soar but I chop that up to working in every part of a hotel.

My boyfriend is convinced I'm pregnant and wants me to take a test, but it was August last year we thought we were pregnant and I had the worst period I've had since starting them. I'm so nervous to take a test and just be told no.
