Bleeding! Help

Rebekkah • First time mom

So I’m going on 6 weeks look about 20 weeks. I have my first ultrasound in a few days. Been cramping a ton. Went out to eat with husband because yesterday and today were so stressful. I over ate and went the bathroom only hurt when I peed and there was blood not a huge amount but like I had got my period and it’s bright red. Went and took a nap so I didn’t worry and 2 hours later peed again and nothing. I’m so scared, an I losing my baby? Is this normal
