I had an HSG yesterday and i have a quest for those of you that have had one.?

Today i have a very thick (sorry tmi) white almost chunky (i am sooo sorry for the level of grossness) discharge. Could this be just reminisce from the test or a yeast infection. i haven't had a yeast infection in so long that i don't even remember. The DR. put me on tetracycline (antibiotic) for 3 days to avoid infection with this procedure. I would appreciate a little word of advice as i will be ovulating soon and this time i am getting preg!!!!!
