Advice on TTC after 2 chemical pregnancies please!!!!

Emma ❤️💛💚💙💜 • Me and my wife are TTC baby number 2 via artificial insemination! :)
Hey guys. So I had a chemical in September, and decided not to wait for a period inbetween. We conceived 2 weeks later and then again I had another chemical (which I'm going through now). 
Every time I have a loss I become more and more driven to have a baby. 
Would anyone be able to advise me on one question though? 
Should I try again straight away before my next period, or wait to try after my next period, so in a month and a half?? There's been no evidence to suggest women do need to wait but I really don't know what to do!
