Pills or D&C

I’m currently in limbo. I’m about 6 weeks but had a lot of bleeding on Sunday. We’re doing betas every 2 days to wait to see if the pregnancy is still viable. The Dr said if he had to guess, he thinks I’m miscarrying. So far I’m just spotting old blood and it had a stringy texture. He gave me the option between the pills or the D&C if it comes to that. This is my first MC, which is the better way to go?
