Week 17 The best moment from one of the hardest weeks

I knew going into this that it wasn't going to be easy. I was fully aware that pregnancy isn't always rainbows and sunshine, but it's part of what trains you to become a mommy. This week, although I had one of the most beautiful moments of my life, has been really hard.
Like I said in my last post I had to have my prenatal appointment early because I was experiencing intense dizziness. There were also a lot of other symptoms I had been experiencing that I wanted to talk to my midwife about. It's been hard to listen to my body because it's hard to tell if what I am feeling is because I am pregnant, and is totally normal, or if it is something that needs to be checked out. Lately I've been feeling like the symptoms I've been having aren't easily summed up by pregnancy.
When I explained to my midwife all the things that have been going on she was a bit concerned for me. She decided to have my chart reviewed by all of the midwives at their meeting. Since then the dizziness has gotten a lot better, but not 100 percent. I do not feel better though. My heart has been having palpitations, and it feels like it is constantly racing. It's not like it disrupts my daily activities, but I have to breath through it and try to calm down. My joints have had terrible pain. It feels like the kind of pain I used to have when I had growing pains, or if I was under a lot of stress. Also, I've been having really terrible, sometimes demonic, vivid dreams that wake me up and make it really hard to go back to sleep. I wake up from those dreams and my body hurts and I'm uncomfortable and I just have to try to block it out of my head. I hate having dreams like that because I know my baby is effected by my body's reaction to the stress. I've also had a terrible time trying to breath still. I feel exhausted all the time from doing nothing and I find myself panting after walking short distances. On top of all of that, I'm pretty sure I have an ulcer. I think I've had it since before Uriah, but it is pretty painful every morning.
It's like my body is under this huge amount of stress, even though my life is happy and things are going so well.
My midwife told me that my thyroid levels came up low in one of my blood panels from my first appointment. She had me go in for another blood test to check them again. I was starting to stress about it a lot because thyroid is kinda a big deal. I googled hyperthyroidism and it was a really bad idea. I actually was under a lot of stress at that point. I got a call yesterday that went to my voicemail telling me that my tests came back completely normal.I'm VERY glad my thyroid levels are good, but then why do I feel like this? It's not twins, and it's not thyroid.... so? If this is all summed up to pregnancy then I'm just going to be happy everything is good, and try to get through it, and hope it is just a phase.
I can feel Uriah moving around in my belly all day, and it really keeps me going. I love feeling his kicks, and I can already tell they are getting stronger. My belly is growing, and although I can't button or zip some of my pants, I love that I can see how my little guy is growing. I love this baby more than I ever could have imagined, and I know that he is going to be just fine growing into a beautiful baby in my womb. One day I'm going to kiss his little face, and all of these symptoms won't matter. It will all accumulate to the sacrifices I had to make (that ALL mommies have to make) to grow a happy baby. I'm trying to focus on seeing his face in October and not about all of these crazy symptoms.
