Pregnancy after an ectopic

Hi guys just after abit of advice really… so I had an ectopic in November 2021 and had my left Fallopian tube removed… I’ve just found out I’m pregnant again… really early on 4 weeks and 1 day, has anyone had a pregnancy after ectopic how did it feel? I’m having abit of pain in my right lower side and worrying a little I have been to the hospital and had my levels checked they are really low at the moment but they said this maybe because of how early I am. I go tomorrow to find out if they’ve gone up or not. Im just sooo worried at the minute and just wondering if anyones gone through something similar and have abit of advice. Thankyou Xx
