Faint lines every pregnancy =miscarriage?

I've had two mc and I've been thinking about it and it seems like every time we've never had a strong positive result. The line has always been faint. Just wondering if anyone had a similar experience both of mine were very early on mc at 4weeks 6 days and 5 weeks 1 day. My doctor kept saying it could be random but I feel like something else is wrong, they were around the same time and the line was always hard to see.

Anyone have any insight or had a similar experience?

I got the number for a specialist but haven't made the appointment yet, & I'm scared of something being wrong so I keep putting it off--I'll do it soon.
