rough day

I've been married for five years. We haven't used protection in all of those five years. We have never gotten pregnant. There was one time that I thought I was. I didn't have a period for three months and did everything from a blood test to pee test and nothing. And once I finally got my period it was the worst period I had ever had in my entire life. Here we are five years later, and we have been trying for a month. I have a lot of friends that are pregnant and my sister in law is pregnant. I start my period on Saturday and so when I went to the dr for some wrist pain, when he asked if there was a possibility I could be pregnant.. I said yea h so he ordered a pregnancy test. Of course it was negative. I cried for like an hour and then made an appointment to see an OBGYN. I'm terrified that there  is something wrong with me. I'm scared that I'm broken. Idk what to do or how to feel.
