Should I take the hint or try one last time

Marie

I’m on my last try on my iud. I’ve currently tried 4 times and all four times my body rejects them by the month or so. I am considering trying on last time but I don’t know what to think. Is my body just faulty? I’m just trying to fix my boyfriend’s and I sex life and I know he resents me that I can’t take birth control anymore due to my cancer. I just don’t know what to do.
