How can i tell the difference between pregnancy cramps and menstrual cramps?my ob confirmed pregnancy on feb.7th at 5 wks 4 days.i had cramps on jan17

Naming cramps...: Pregnancy cramps happen only when pregnant. Otherwise, they are not called pregnancy cramps. Menstrual cramps cannot happen when pregnant, because pregnant women do not have menstrual cycles (they do not menstruate while pregnant). If cramps are during pregnancy, one can call them pregnancy cramps whether they feel like menstrual cramps or like pregnancy cramps (they likely feel similarly).
