Possible miscarriage?

I accidentally walked into the side of a door the other day. There was no immediate pain but that night I woke up with shooting pains that went up to my back. It only lasted a few seconds and went away as soon as I changed sleeping positions. The next morning I was more nauseous than usual and vomited (I haven’t had that severe nausea before) and have had headaches the past couple of days.

Could this be signs of a miscarriage? I haven’t bled at all and my boobs are still sore, plus I still have slight nausea in the morning (just not throwing up) so I’m hoping there’s nothing to worry about. Thanks in advance!
