Struggling to understand this cycle

So I had a miscarriage at 6 weeks & 4 days on the 11th December, I want to try again as soon as possible but I’ve not got my periods back yet & was wondering how long it took for you personally to get back to normal, also the bleeding stopped after 4 days and I was getting negative tests 10 days after. When should I start ttc, is there a chance I could be pregnant again with not getting my cycle back? Any help is hugely appreciated
