Pregnant after ectopic

I am 4 weeks, 1 day pregnant with baby #3 and our second pregnancy (first was a chemical, ended around 4 weeks) since I had an ectopic pregnancy in July. I am terrified. Ever since I found out, I have had “cramping” or like a dull sensation where my right fallopian tube is. I lost my left fallopian tube in surgery in July due to the ectopic. I am so anxious that I’m having another ectopic pregnancy and that my doctors won’t catch it soon enough. They’re checking my hcg, but my hcg was normal with my ectopic.

Has anyone had this happen? Is it normal to feel your other tube in pregnancy?
