^ hi sis. I had hssg (SISH) a few months back. i'd say it's safe naman, basta magaan ang kamay ng sonologist or OB na gagawa. it's a bit uncomfortable, and you could feel some pain similar to PMS after the procedure. pero over-all, okay lang. i think SISH is more uncomfy, since they needed to fill my uterus with saline solution, to the point na parang puno na sya. for regular HSSG, i dont think they need to do that. yung sa akin kasi, they needed to know how fluid flows inside.
i had mine in Delgado Hospital in Kamuning. If my memory serves me right, around 2800 yata yun, am not really sure kasi kinover sya ng HMO ko. If you have an HMO, you can ask if they can cover this for you, tapos ipalagay mo sa diagnosis for endometriosis (some HMO sees this as infertility test kasi).
