subchorionic hematoma bleeding

I’m 11 weeks pregnant and at 9 weeks they told me I had a small subchorionic hematoma. My OB told me it was nothing to worry about and may have spotting. I had sex last night and woke up bleeding I have been bleeding on and off today. Not filling up my panty liner only when I wipe. Still it’s scaring me. They can’t do an ultrasound until tomorrow morning. I’m upset with myself mainly for not researching more but the on call Ob told me she tells her patients to not have sex ... my Ob didn’t share this with me.

Has anyone experienced this? What was your outcome I’m so stressed and scared right now.
