Painful cramps 22 weeks

So last night I did iv therapy this was my first time since I was hospitalized a few weeks ago because I’ve been trying to figure out work time off. After I left iv my arm felt wet I pulled my jacket up and I had totally bled through the gauze. Finally Got it to stop in the bathroom. I left the hospital and I got to my car and I felt so so tired. I only got fluids, no medicine. I sat in my car for like an hour cause I didn’t feel safe to drive and noticed one of my eyes was blood shot. It’s better now. And when I got home I was so shaky. Not cold. I called my ob and she just said to eat some protein so I had some chicken and potatoes and I’ve been drinking some coconut water, water and Powerade. I felt pretty light headed and so I went to lay in bed early. I slept and woke up my arm is super sore, she had to poke me twice once in my wrist and then that blew so my elbow. So I kinda expected that. But I had a ton of Braxton Hicks last night. Im timing them cause they are watching that. I had one every 20 minutes lasting about 45-1 minute. For almost 2 hours til I fell asleep then idk. I keep having cramps like period/poo cramps but my stomach isn’t getting tight. But I don’t feel like I need to go either. So I’m just chilling. The power is out here so I can’t work but I’m not sure if this is all just normal stuff of if I could be having a reaction to the iv or something idk. I hate being the dramatic first time mom that calls in all the time.
