I recently got off my depo shit. I stopped taking it in December and finally got my period in December. I have been having unprotected sex. I missed my period and have been experiencing minor cramping, lots of gas, eating a lot, light headaches here and there, long naps during the day, difficulty getting comfortable at night to sleep, slightly sore nipples, I had light bleeding about 2 weeks ago, shortness of breath at some times as well. Could I be pregnant even though I just got off depo
