Hi! I’m not even sure you’re even going to read this or answer me considering the ones I’ve seen have been over a year ago. About a week ago my guy and me have protected sex, condom only...for now. My period was suppose to come earlier this week but it has not come yet, I have all the signs that I would get before my period yet no flow. Should I be worried? I’m only 20 and have no thoughts yet of having kids.
