How far along am I?

Sarah

So I miscarried back in November. I never had a cycle before getting pregnant again shortly after. I know you can find your estimated due date by counting from your last period, but I never got one, so what do I base it off of if I never got a period before getting pregnant again? When I got my blood work on Tuesday last week, based on my hcg levels I was around the 4 week mark, but is that accurate to how far along I really am? I don’t want to wait until my next appointment way later this month to get an estimate of my due date 😭
