Kybella if I am pregnant/trying to conceive?

I am wondering how safe Kybella is while trying to conceive/while pregnant. I'm going through fertility treatments now but have a Kybella voucher that must be used within the next 3 mos. I can't find any information on any risk factors. Has anyone heard of any reports on tests or clinical trial reports? Lastly, since what I gather might be a risk is the acid injected - how long does this stay in a person's system if I decide to get the Kybella treatment and then resume my fertility treatments?
