Loosing the baby or loosing my mind!

Being 20 years old, in the service, and being alone feels so hard . So 7 days ago I started bleeding and feeling cramps. And I just had my period a little over two weeks ago. I figured hey I could be having my period again due to the fact my job is stressful. And after three days of non stop bleeding I decided while my boyfriend and I were out for date night we should pick up a test. And I went home and took two of them! BAM! Both came out positive. But I didn't feel right. All this bleeding and cramping ans back pain and my body felt weak. My one good friend and boyfriend came with me to the E.R. At 1 am. I did the peeing in the cup and they took my blood a lot! Well the doctor comes in to congratulate me on my baby and say I'm pretty early along and I ask about the bleeding and she checks my pelvis. My cervix is closed and that means it's just a threatened miscarrage. I'm already freaking out knowing in pregnant and I have no family near me because I am in the military and move around. I felt alone. I go home and relax and wait to go back for them to take more blood. Went back yesterday they said they would tell me today if I am loosing my baby or not. And I got nothing today no info, nada. My back hurts really bad and my cramps are no better and I'm still bleeding. Idk what to do. My boyfriend is trying the best he can to be supportive and make me comfortable but I feel so alone I told my parents and siblings. And I just feel lost I don't know what's gonna mess me up more if I loose the baby or if I am still pregnant and have to worry about what might happen to the baby. And all this isn't helping at work because being in the military I have certain requirements and I feel like I can't tell anyone till I really find out what's going on with my body. I just feel so emotional and confused!
