Your 3-4 weeks X as 1-2 weeks on a digital mean you consieved 1-2 weeks ago x
Probably around 3-4 weeks however there’s no way of telling until you have an actual scan as the weeks indicator is based on your HCG levels and everyone’s is different. As far as I know they’ll probably use the miscarriage date as your ‘last period’ and works your dates off that until you go for your dating scan x
This was my exact case. I contacted my doctors who referred me to EPU. If you go in and get HCG reading they should be able to book you in for a scan and tell you how far along you are approx xx
You typically get a positive test 11-12dpo if that helps? So you’d be 3/4 weeks
