hello... I've been taking DMPA since october and had taken again just this January 3, 2014 since DMPA is valid only for 3 months. Just this January 2, 2o14 my partner and i were having sex contact but I worried a lot if I'll get pregnant since january 1 is the sched of injecting some DMPA but i take the next day which is on last january 3, 2014. could i be pregnant? i had a 9 months old baby girl that's why I would like to be protected. I was suspecting because my abdomen was cramping, and my tummy's like something's moving and can feel somewhat like a "heartbeat" and then something kicking my tummy also looks bigger. pls. help me.... I need your info's. thank you....
