2 losses in one year

In December 2015 I found out I was pregnant with my now ex husband. In February I had my first appointment. We went in for my ultrasound and they said they didn't see a heartbeat. My heart sunk and I started crying and asking what do you mean. They told me either I'm having a miscarriage or I'm just too early and just sent me home. Later in that same day I started sporting and freaked out. My ex and I went straight to the hospital and there they told me for sure I was losing the baby. It was just a matter of time before the baby came out by itself. They told me I could either get surgery, take a pill, or have it naturally. I chose naturally. About 2 weeks later I was in excruciating pain. I had to drive my mom to the airport because my ex wouldn't do it. She had to fly back home so she could go back to work. So I drove her there and called my doctor and they said it was happening. I was losing my baby. They called me in a prescription for the pain and told me to make sure I didn't lose too much blood and if I did then go straight to the hospital. well I could barely move but I drove myself to get my medicine and called my ex and explain what was happening. He told me "I'll be home when I get off work" his Sgt knew what was going on and told him if he needed to he could leave. He chose to stay at work. As soon as I got home I went to the bathroom and it hit me. I started bleeding nonstop for an hour. once it finally stopped i was able to make my way downstairs to get my medicine and at on the couch. I was weak I could barely move. he finally comes home and my pain meds kicked in and he tells me "you look like you're feeling better wanna go bowling" and I'm like are you serious right now!? but I was so depressed and knew i had to get out of the house i we went and met up with people there. one person came up to me and asked if I was okay because I looked extremely pale. I told her what happened and she said I should of went to the hospital. I told her I could barely move there was no way I could drive. well we go home and i try to talk to him but he just repeatedly tell me it happened get over it and deal with it. well I couldn't. we ended up splitting and a few months later I found someone new. well in December 2016 I found out I was pregnant. I freaked out. I had only knew this guy for 4 months and I didn't know what to do. he was really nervous at first but then came around. well the day after Christmas I found out I was miscarrying again. I felt like I could never have a baby. the one thing i want most I can't have. I went to the doctor to see if they could run tests to see why it keeps happening and all they told me was just try again and if happens again they will run tests. well here it is at the end of 2017 and I'm so nervous to be pregnant again. if I do end up pregnant will it just end again? will I carry full term? so many questions run through my head. I've been having symptoms lately and I'm so nervous. ive been extremely tired and moody and hungry and having random pains everywhere and I just dont know what to do. sorry for this long post. I've never really talked about this before and I just needed to vent lol
