Sorry if this is a very stupid question . Period due 3 days ago and have been cramping for over a week and a half so kept thinking period due but then it never came. Usually I get cramps the day before but not earlier. Other symptoms are mild nausea (but only occasionally) and sore nipples (again for a week and a half but less so now). Can I be pregnant and just not enough hormone in my urine yet or does a negative after period due just mean that I'm heading for a late period (only been off pill a few months)? Thank you!
