I'm going to sue the hospital!

Demi • My First Born Child Kairo 💙
I'm so fuming with my hospital! 
So On the 13th of February I had my 21 week scan and everything was perfect except from my sons left kidney there is mild water on it ): 
It's not the worst thing to happen but I am still worrying. 
I'm a first time mum and I just want the best. 
I also haven't been feeling to well myself... I've been burning up to the point I feel like passing out and really bad nausea. 
I called triage and spoke to a nurse and I explained the situation and how Unwell i have been feeling. She looked on my notes and said "No wonder why you've been feeling like that" I said pardon? She said Demi you have a water infection two! 
Who else would SUE?!! 
I've been like this for almost 2 months without being told what's wrong with me even though tests were done both midwifes before this said I was fine!😤 
Almost two months later I'm being put on antibiotics!? This could have caused serious problems for both me and my son. 
Should I call a lawyer? Need advise please ):
