Hi! my friend is worried that she is pregnant. She had normal period but haven`t had her period since the start of october, but she have had her period before that regularly. The thing is that she haven`t had sex for about 5-6 months. Could it still be possible that she is pregnatn if she have had her period regularly until october. She is not big or gained much weight and since october she have changed her eating habits. And could changed eating habits delay the menstruation period?
