subchorionic hematoma

Kim

I had a large blood clot fall from me Sunday morning and bleed for a couple hours after then stopped so I made a dr appointment on Monday and dr thinks I had a subchorionic hematoma but can’t be certain ( that’s what he said ) he did a ultrasound and baby was still there and had a good heart beat I started spotting Monday evening and it stopped again well now I’m spotting again and having mild cramps ( its Thursday )... my question is has anyone experienced this? He also has me coming in weekly for ultrasounds for reassurance... I will be 12 weeks on Saturday
