Foods to help missed miscarriage continue naturally?

At my 9 week scan last week, the sac measured 6 weeks and there was no heartbeat. 😞 I started spotting today, so I guess this is really happening. 🥺😭

I'm wondering if anyone knows of foods I can eat to help encourage uterine contractions? I've read that pineapple and papaya should be avoided during pregnancy, so I assume they may be helpful in this situation?
