hi i need help. i recently got off the pill in october and i had sex but used a condom and then i bled every other week for about 3 weeks then i stopped and i havent had a period again since. im having cramps but no bleeding. im scared and i dont go back to the doctor for 2 weeks? could i be pregnant? or is it jsut my body adjusting? i was on depo for a year then switched to pills. idk whats going on with my body,
