Am I overreacting

Update*******

So I went to the doctor last week for my appointment and it went very well. I told him all my concerns and even cried a bit because I'm scared. He talked in a comforting kind of voice and really talked with me about what's going on in my body. He told me what I have is called round ligament pain and even though there's no way to help that medically, he found me a website and told me to look at the exercises and try them out. My son is getting stronger and that is also why I have been having bad pains as well. My son kicks and I can feel he is kicking hard. I also told him about my lightheadedness and how I almost blacked out and he said for me to sit down anywhere anytime I feel like that and to breathe. He said it doesn't matter where I sit it can be anywhere even in the middle of the store I need to make sure I'm ok before I move. He told me about some medicines I can take and if I do go unconscious to go to the hospital. He checked my son's heartbeat and while I was lying down he offered me his hand and helped me up. I think maybe there needed to be more advice and more communication between me and him. He really turned out to be a nice guy and he actually calmed me down about what's going on. Thank you everyone for your support and I hope this update clears this up. Wish me luck♥️

Ok so this is my first pregnancy, I am currently 23 weeks pregnant with my little boy. I have been experiencing horrible stomach pains all over my stomach to the point where I do not work because I end up breaking down crying and now it doesn't matter what I am doing I still get horrible stomach pain even while sitting and I cry it hurts so bad. This has been going on for 2 months now ever since the beginning of my second trimester. Now my vision gets blurry to the point I'm about to faint and I have collapsed barely making it to my couch. I was just standing making dinner and all the sudden I lose my vision and I get dizzy if my husband was not in my way I wouldn't of been able to push off of him to make it to the couch so I don't hurt me or my son when I fell. My obgyn does not see this as a concern. No one at the office I go to sees it as a concern. They said it's normal to feel this and they know how extreme it is because when they press on my stomach it hurts me and I shed tears. I feel I'm not being taken seriously and I have been told that what I'm feeling could be signs of low blood pressure or worse. But I'm not sure on blood pressure since I am always getting that checked and I'm told I'm fine. I'm so scared I don't know what's going on and I just want to know if I'm overreacting on my obgyn and how they are treating me. I made it a point to tell them I hurt so bad and all I was told was it's going to get worse. Please help I'm 18 and this is my first baby I don't need criticism for my age I need help understanding all of this.
