Horrified and sad

I had never been pregnant before. My husband and I have been together since we were in high school (17 years old). We got married at 20. We were going to start trying at 25. Were 24 almost 25, we were getting a little reckless because we were tired of waiting. Both our families are strongly expressing how they want a new baby around. In my family the pregnancy tests don't work till your at least 6 months. I was having very weird periods,so I took a few tests they were all negative. I told my husband I was feeling a little strange and that maybe I was pregnant. He said I was just overreacting to my weird periods. My mom had a suspicion and so did I. I was throwing up at night but I just thought it was acid reflex. I was 6 days late. I felt a little bit of movement a few days before it happened. That was when I was trying to tell my husband but we got into a huge argument with him telling me to take a test. I did and it was negative still. A few days later I got ready for work and I thought I was having my period. I went to work, cramps and all; came home, took a hot bath,and went to bed. I woke up coughing because I had a dry mouth. As I coughed I felt a rush of blood come out. I thought wow Im heavy. I had my husband get me a roll of toilet paper and a plastic bag. As I started cleaning up I didn't feel right I went to pull off my bottoms and I looked it was horrifying. I thought this cant be happening to me its just my period. I told my husband to run me a bath for easer clean up. On the way my husband told my mom that I was bleeding very bad and my mom called me and asked if I needed her, I said yes and my mom came running. As my mom was at my door it came out my mom took a look and tried to hold her self back from tears but I could tell. It was about 6inches. I knew then what was happening to me. I was light headed, dizzy, and throwing up and the blood kept pouring. My mom told my husband what was going on. He was in shock. Because the blood didn't stop my mom told my husband to take me to the nearest hospital. I had a mental breakdown in the car on the way to the ER. I was at least 4 months pregnant. When I got to the ER, it was very hard and embarrassing to explain but I did. The two female nurses started grilling me on how I knew I was having a miscarriage if I didn't know I was pregnant. And if the tests were negative it was just my period.They acted as if that is normal for a period. But it was completely not normal for me. The guy behind me was there for a nose bleed and they didn't question him at all. It was humiliating. I waited for two hours to get my results from the blood test, there it was "pregnant". They sent me home and told me that if I feel sick at all to come back. It was 3am I was tired,emotionally drained, and hungry. My husband took me to get food and we went home. When I got home I saw my mom was still up and had been crying. It hurt to see her hurt. My husband was in denial till he realized it was his baby and he also went through a miscarriage with me. The hardest thing ever is my dad has been bugging me to make him a grandpa how do I say I had your grandbaby but now its gone. And now all I want is my baby back. I keep asking my husband if we can try and he keeps telling me to give it time. I didn't get sick and I did go to my dr they checked me out Im fine. I had my first period since and guess what it was perfectly normal.
