Okey Condom Causes Unwanted Pregnancy

I had been using birth control and was under the impression that I wouldn't become pregnant, but for some reason, I did, and I'm still in disbelief about it. My mental health is in a shambles, and I have no idea what to do about it. Never in my wildest dreams did I imagine having three kids. This is a completely unacceptable situation, and as a result, I'm thinking about taking legal action. The fact that this took place despite the fact that I was using birth control is beyond my comprehension. I am very interested in hearing about the potential resolutions that you have for this difficult circumstance.
