Maybe pregnant before period after miscarriage

We’ll see. Last time I had implantation spotting 3 days after ovulation (usually it’s 5-7 days but I’m very aware of my cycle and my doc never changed my due date from my conception calculation.) well here we are 2 weeks of no bleeding post miscarriage and I’m having random spotting 3 days after ovulation. And I never spot. If I’m blessed with another pregnancy I’ll be happy but I really don’t want to be going through all that pain again in 2 months or whenever. I already have 2 miscarriages under my belt at 23 and with my birthday next month I’d hate to make that 3 before I’m even 24 years old.
