feeling frustrated.

I waited 3 years for my BFP. Countless amounts of let downs and negatives. Feeling hopeless, and even useless. Then it happened when I least expected it. I found out at 4 weeks. Then the trouble began a week later with my first trip to the hospital with bleeding. Baby was fine, they even got a heart beat. Blood work great. Left with no answers. Went to the doctor a week later and they found a polyp, thought maybe that was the problem. Bleeding continued on and off. I went the week after, then two weeks after that, and then back a week after that. No word of the polyp again. Finally it stopped. I was relieved. But it sure was short lived. 12w 5d I had some discolored discharge. Within two days it was spotting again, went to the doctor and he checked my cervix and thought it was soft. Went in for an ultrasound and found out my cervix was short. He wants me back weekly until we get it sorted out. Next week if it hasn't changed, or has gotten worse, meds and restriction. Later, a stitch on my cervix and bed rest. 

Anyway, woke up this morning and was bleeding again. Tried to wait it out to see if it got better on its own, and it didn't. So I call my doctor and let him know what's going on, and he tells me to head on to the hospital. I get to the hospital, ultrasound, blood work, and urine sample. The doctor comes in with all the test results doesn't listen to anything I have to say, and says all is okay. Walks out. That was the first and last time I saw him. Then proceeded to sit for an hour and a half waiting to get the needle out of my arm and to go home. Once again with no answers. All I know is the baby is perfectly okay. Which don't get me wrong, that's enough for me! But I can't shake the feeling that if I'm still bleeding, still having some cramps, will something go wrong? I'm so ready to walk into the office and the doctor to be like okay let's figure this out, and comes to some kind of conclusion. Why does no one seem concerned? Why does it feel like no one is doing everything they can? I know it's a waiting game, to see how things go. But I'm almost 14 weeks with barely any knowledge of what's going on. Sorry.. I don't want to worry my family with this, my friends haven't had any where close to the same experience, and my fiancé, as much as he tries, just doesn't understand. I don't feel like I have anyone to talk to.
