Hello~I think you need to talk to either your GP or a gynecologist. Having just 5 periods a year is not normal, you need to possibly have some hormone tests done and possibly an ultra sound to check for ovarian cysts. As to the stomach making sounds, this is fairly normal, and for some people, having a BM three times a weeks is normal, but actually, it is better to have them more than that. Again, mentioning this to your GP is advised.
