Is this considered as a miscarriage?

I’m 5 weeks 2 days pregnant.

My partner and I had a pretty big argument yesterday that lead to a lot of emotions coming from me. A few hours later I start spotting, mild cramping and lower back pain.

This morning the spotting is a little heavier but not too much like what I would normally get when I’m on my period.

Has anyone been in this situation, if so how long did the spotting last? Did you go see a Dr straight away? I’ve got one booked for Monday to confirm the pregnancy and get a referral for an ultrasound sound, but should I go earlier?

Any suggestions and experience would be very much appreciated.

Thank you in advance
