The main use of Profasi (human chorionic gonadotrophin - HCG) is in infertility due to impaired ovulation (i.e. formation of female egg). However it is also used in corpus luteum insufficiency, a substance needed to hold pregnancy. Apparently your gynaecologist considered the importance of maintaining pregnancy vital due to previous miscarriage (even though due to ectopic pregnancy) and your age (pregnancy becomes a difficult proposition in 35-year plus females who have not had a baby before) that she/he did not wish to take any chances whatsoever. Now that you have already taken eight injections, you should abide by your doctors advice. Profasi can cause mild to moderate abdominal bloating but it is of no consequence. While it is good to get as much knowledge about the medicines one is consuming, internet information is sometimes insufficient and even misleading. There is no ethical regulatory mechanism to check information that is uploaded; so one has to be careful.
