|Zeddd, masturbation, sex and orgasms does NOT affect your menstrual cycle. Just like rubbing any other part of your body does not affect it. Just the opposite is normally true, certain phases in menstrual cycle can affect your desire for sex and orgasms. For example during ovulation or before your period.
Was your cycle regular at some stage? Are you old enough to expect a regular cycle?
|Zedd, at almost 18 your cycles should be more regular. Various things can delay it, most of these affect your hormones. Your cycles are almost completely controlled by your hormones. Things that can affect your hormones:
Low body fat
Stress and worry
Conditions like diabetes
Pregnancy (masturbation cannot get you pregnant however)
Anothr culprit is ovarian cysts (PCOS/PCOD). If you are overweight, have an enlarged clitoris, having extra body hair growth (face/hands/arms) or hair loss (in the same pattern as men does), there is a chance that you may have PCOS.
A doctor will need to examine you to determine why this is happening.
Best of luck!
|The medicine is more than likely plain birth control pills. These are used to control PCOS.
PCOS is the reason for your lack of period and it needs to be treated to reduce the androgen hormones in your body. Please talk to your mom again.
