I think this is it....well I'm hoping this is it

So me and my boyfriend have been trying for quite sometime to have a baby and everytime we think that we are pregnant the tests are negative. Well, I have not had a period since February 11th and I have had some crazy mood swings and I am very bloated and tired all the time and so on and so on. I was talking to my cousin about our work outs and he was like, "I have noticed that you seem to be getting bigger, I think you need to take a pregnancy test, even if I have to buy it for you." I havent talked to my boyfriend yet bc I want to be sure that I am before getting his hopes up again. I am just really hoping that I am this time.
