How to encourage passing a MC

Hello ladies. My first appt and U/S yesterday showed an empty gestational sac measuring 6.5weeks. I should have been 9w6d. The doctor told me I should wait a couple weeks to see if I pass naturally, and if not meds or D&C become options. I spotted brown during week 7 and had one short instance (one wipe) of clotted red spotting during that time. Looking back that should have been a red flag. Anyways-- do you have any natural herbs or something to help encourage a miscarriage to pass? I hate being in limbo and I'd like this to go quickly. I'd really like for thiso happen naturally as well. I'm very depressed and would feel better knowing its out and I can turn a new leaf. Thank you❤️
