Complications (I just need someone to talk to)

Is anyone else having complications with their pregnancy. I'm 18 and 4 days and I kid you not I've been in so much pain. Only for the doctors to tell me that there's nothing wrong that it's just growing pains but I just feel like something is wrong. There are some issues I'm having though and I'm wondering if it's just stress that's making me this way. My pressure is always through the roof which causes me to have constant migraines and they gave me medication for it but it only makes me sick. I have to do a blood test over twice because my tuberculosis test came inconclusive. Went to do an amniocentesis but that got screwed up because as she was inserting the needle I threw up all over the place; I guess I was too nervous. Is anyone else having complications or are everyone's pregnancies going well
