Symptoms

I need some reassurance if it’s reasonable. I am close to 5 weeks pregnant, found out 1 week ago. Today I started having cramping similar to my period accompanied by some major bloating and back pain. It was quite strong for about 30 minutes but now has been intermittent and light the last few hours. Is this normal? I am so scared I am miscarrying. Every time I go to the bathroom I check if there is blood, but nothing. My cervix still feels high. It took us 2 years to conceive and I am just so scared a miscarriage will completely break us. Anyone with insight?
