Abortion regret

So I had a medical abortion starting Thursday into Friday and I’m 17 and I didn’t want to do it but I was talked into it. I thought I was gonna be mentally fine but I’m not I cried every night besides one night cuz I thought I was strong enough. I’m not strong and I flipped out on my bf over something stupid which I normally don’t flip out over about. We aren’t talkin but I want to tell him how I feel and idk should I tell him tomorrow or tonight about the abortion situation. I highly regret it and I’m typing this balling my eyes out. I’m looking at my ultrasound and I would’ve been 8 weeks in 2 days my baby had a heartbeat and I brain. I highly regret it.
