So currently I'm in the UK while my girlfriend is back home in the US. We have been away from each other for almost three months, and we have never had sex. She has had normal periods for the past 2 months, but this month she is almost a week late. I can tell this is really starting to bother her because she is going through all of the symptoms (bloating, fatigue, cramps, etc), but she is starting to get concerned cause her bleeding will not start. People have been starting to worry her with pregnancy scares, which I've told her is impossible because we have never had sex. I honestly feel it's stress, and I have been trying to calm her down. Also over the past week she has had changes in her diet and exercise routine. I'm just really worried about her, and I want her to feel better. Does anyone have any recommendations on what she could do to feel better, because I really want her feeling better when I come home for Christmas? Any help would be appreciated.
