I have similar symptoms, except for the varicose (and possibly the breast) one... The only difference is that I am still a virgen, no intercourse nor having a Penis near my vagina, so Im quite scared also, my period comes about in a week, can someone please answer this?
Talk to your health care provider. There are such things as a phantom pregnancy where your body believes it may be pregnant especially if you have mentally convinced yourself. I'm not saying this is what is happening to your body but I would definitely talk to a doctor. It could be stress related or anything really.
