Anxiety meds

I’m 9wpp and the last few nights I have not been able to fall into a deep sleep and it may be partly due to my LO waking so much lately, but since I am not sleeping well and not falling into a deep sleep I now am having really bad anxiety which is making sleep even worse. I have a script for klonopin 1mg that I have always had prior to pregnancy and I know you can’t take it while pregnant or breastfeeding but I really need to take just one dose to reset my body. I’m unsure how long I have to wait before I can resume breastfeeding. I have milk in the freezer I can use but if it’s a wait time of like a week then I can’t do that. My doctor that prescribed them doesn’t seem to know much about how it effects breastfeeding just that I can’t breastfeed while taking it. Anyone with experience taking this?
