My concern is about my girlfriend's menstrual cycle. I consider it to be really long: 40 days mostly. Is this normal? I also would like to know if women always experience pre menstrual symptoms. My gf does, but this month she isn't having any.

We "play around" a bit but as usual we didn't have intercourse at any time (I was dressed and she was naked). As i read previous questions about precum and sperm, there is really low chance of a pregnancy but i'm a little worried though (mostly because of the lack of symptoms). She started excercising daily two weeks ago. Might this had altered her period? She isn't late yet but i have the feeling she will.

Thank you very much for helping me and others.

As for a 40 day menstrual cycle being normal? I first need to know what you mean by menstrual cycle. I am interpreting that you mean that there are 40 days from the first day of her period one time, to the first day of her period the next time. And if that is the description you are using the word for, although 40 days is on the long end of the continuum, it is not anything to be concerned about. Many women have 40 days in between periods. The fact that it is regularly like that supports its normalcy for her as well.

Not all women have premenstrual symptoms, and some will have them one month and not another. Premenstrual symptoms are caused by hormonal amounts and changes and can be altered by so many things, including exercise, eating habits, stressful situations and more. The lack of symptoms is not related directly to the presence or absence of her period due to pregnancy. It is not at all likely, given what you described to me, that she is pregnant. The exercise could remove some of the symptoms though. In fact, one of the suggestions to relieve a woman of those symptoms is exercise - so this may be exactly what happened here.

Thanks again for writing and write again if you have questions.
