hi when its comes to women being pregnant it can happen all sorts of ways even when on bc but if you mean an iud then it does get a bit tricky it means it must have slipped out a bit for it to happen. but it is possible for a women to be pregnant and still have a period or periods even if it sounds odd. i think the best thing for you would be see your doctor and get a test done there. hope this helps a bit. good luck
could i be pregnant even though i'm on birth control and have not missed any periods? . my daughter is 4 years old and i have been on the mirena since. i have not missed any periods (i also just got done with this month's period and they have been normal) but yet i always feel "full" but not quite bloated. my stomach has just felt different to me and i feel little quivers in my abdomen. i have also taken 2 pregnancy tests which both came up negative. could i still be pregnant? could it be something more serious? i have tried calling my doctor for 2 weeks now with no response.
