If there is any chance that you may be pregnant, take a pregnancy test, just to be on the safe side. However, it is probably just that you had a shorter period than normal, for no explained reason. If it happens again, go and see your doctor
Yes. The same things happens with my girlfriend. Her breasts become very sensitive a few days before her period.
You haven't started puberty yet!
Unlikely. It depends if your periods arrive.
Your breasts may be tender starting normally 1 week before menstruation usually ending within one to two days after beginning. This is what my female patients have told me.
Swollen or tender breasts can appear as soon as the day your period is due or even earlier. Early pregnancy and pre-menstrual symptoms are very similar, so tender breasts may occur up to a week before your period is due. A pregnancy test will confirm one way or the other as soon as your period is late.
No you get breasts first
Normally they feel tender at times of menstruation and if I'm remembering correctly they are also slightly tender at times of ovulation as well because of the hormone changes.
Typically, your breasts start to develop about 2 years before your period begins.
I've always had sore breasts right before my period and I'm only 19, this has being happening since I started mine.
No.
Your breasts can seem to get bigger before menstruation. Hormonal changes can effect the breasts, causing breast ducts to swell, so this cause cause temporarily larger breasts during menstruation or just before menstruation.
Most girls start their period when they are 12-14, but you can start as early as 8 and as late as 18. I started my period when I was just 10. You're breasts start developing 2 years before you have you're being the onset of you period (usually). If you haven't started and you're breasts have been growing for 2 years you should see a doctor.
