I Am 36 Weeks Pregnant. Started Going Into Preterm Labor

I am 36 weeks pregnant. Started going into preterm labor at 28 weeks, stopped with 48 hours of mag and bed-rest. Then again at 30 weeks, stopped with one shot of Terbutaline, IV fluids and bedrest. About 3 days ago I started having really heavy d/c, it's slimy and greenish-yellow. I noticed today that I am producing an odor. You know that smell you have after you have a vaginal delivery? I smell like that. And I am taking 2 showers a day due to back pain, so it's not that Im just dirty down there. Is this something I should be worried about? My friend freaked me out saying that that smell is caused by my uterus compressing and trying to get rid of remnants of placenta.
