You need to make an appointment with your Gynaecologist.
I had protected sex twice. My period was late, but when I got it it was extremely heavy. My cramps were so painful they caused me to throw up multiple times and I filled two tampons within 3 hours. After that, my period became very light. Help?
You shud of not been have sex in the first place thats your falt
I think you should visit your gynecologist; either if it's for the doctor to tell you you are fine or if it's for your doctor to diagnose some kind of trouble and then fix it.
Your diet is off. Eat more healthier. Take suppliments to fill in the blanks. Increase magnesium and omegas before your monthly.
I don't think there is anying to worry about. Your body just needs to get used to you having intercourse. Same thing pretty much happned to me when I lost my virginity. A penis is a fforeign thing to your vagina right now. Don't worry you will be ok.
