Last month I got my period two times, at the beginning of the month and at the end of the month. However, this month I haven't gotten it and I am two weeks late. I am having cramps and it feels like im on my period, but i'm not. I have not taken a pregnancy test. I am 19 years old. What are the reasons for this??
Well, first of all - did you have unprotected sex so you could think that these period changes might be caused by pregnancy? Second, was your period ever irregular like this before? There are other reasons that can cause these irregularities in your menstrual cycle besides pregnancy - any kind of hormonal imbalance could lead to this. And there are number of reasons why hormonal imbalances happen, from stress, change in weight to taking antibiotics or having some kind of infection, sexually transmitted or not.
