Min... mine is similar to Strawberries, just that mine is a 450miu pen, her's is 300+ I think different medication. Is yours gonal f too?
Strawberries, did your doc increase dosage? HSG is crampy, I wouldn't say its painful but it is more uncomfortable than papsmear cos they need to open up the cervix. When the dye goes in, there will be a menstrual cramp feeling, if no blockage, the feeling will go off. Then after that will be just now and then got abit of cramp but not severe. However, the dye will flow out and you will bleed, hence bring a pad in case the hospital doesn't provide.
KitKat, rem to take panadol 1 hr before the HSG and bring a pad in case the hospital doesn't provide. Don't be scared, it will be over in 30 mins. All the best! Rem, no sex before that......
