TW possible MC?

For those of you that have had m/c how long did it take for it to start? my quant from 2/20 122.7 dropped to 99.0 on 2/25. Now with my last mc in 2022 I bled pretty significantly right after I started spotting. I still feel pregnant af, sore boobs, nausea at points during the day and fatigue. Took a test yesterday and it was super dark right away. I’m still spotting on and off and cramping here and there but only when wiping.

*technically* once numbers start dropping they drop at a 50% rate every 2-3 days, just opposite of the doubling factor. So realistically it should be around 12 right now? (More blood work tomorrow) I’m also scared I have retained products and I’ll need a DNC and that’s why I still feel pregnant. 😭😅

Anyone have experience with this? Did it take a while for you to actually bleed? I would be 6w3d today.
