No. Sounds to me like you are feeling the ovulation. Many women get an ache during ovulation. Even though your tubes are tied you still ovulate.
its definitely a female problem,you're either pregnant or could have a csyst on one of your overies and could just be stressed?
Yes if after your period but if seven days before your period you will not become pregnant...
No, you don't have to get your period to get pregnant. Menstruation occurs after ovulation, if the egg is not fertilized. Thus you could get pregnant before you ever start menstruating as you could be fertile before then.
no
Yes, there is a high chance that she could be pregnant
If you have missed your period and are pregnant, you most likely got pregnant around 14 days before your missed period.
You could well be.
If she has had her period before, then yes
It is possible, but extremely unlikely.
no
