Need some cramping reassurance 🙏

I had my first positive pregnancy test a week ago, (took several tests including a weekly indicator, which said 2 to 3 weeks) so roughly 5 weeks now. Been having cramping every day since I took the test, feels exactly like my period pains with a heaviness in the bottom. They are not painful cramps, but I know they are there. I am filled with anxiety about ectopic pregnancies and miscarriage. I’m also in complete disbelief because we have been trying for three years. any form of reassurance would be greatly appreciated ♥️
