Hi Dr. Purushottam welcomes you to HCM virtual clinic! Thanks for consulting at my virtual clinic. I have carefully gone through your case, and I think I have understood your concern. I will try to address your medical concerns and would suggest you the best of the available treatment options. Actually if you have 8 weeks pregnancy I will suggest you to get USG done ; if it shows normal pregnancy inside the uterus then you need not worry about ectopic pregnancy. Ectopic pregnancy- pregnancy growing in the tube- usually presents with following symptoms-- !) missed periods 2) pain in lower abdomen 3) episodes of black out - giddiness 4) vaginal bleeding 5) USG shows empty uterus and some mass on its one side with or without fluid/ blood collection inside pelvis or abdomen. And the shoulder pain you are describing is due to excess blood inside abdomen which reaches and irritates diaphragm and liver. So first of all get USG done , and if it shows normal reports please do not worry. I hope my answer helps you. Thanks.
