I had my HSG test done one the 28th of Feb. two days ago i had some stretchy mucus ( which was my predicted ovulation day) and i also had a little yesterday as well, today i had very light spotting (only on the toilet paper the first wipe) a little more stretchy mucus but was cloudy and i almost feel like i have a yeast infection coming on, i was prescribed a antibiotics the same day as my HSG and was told to start taking it and i just finished it yesterday, could this have something to do with it? Or could it be something else? Too soon for implantation bleeding?
