My shot was due February 13th, and I still haven’t gotten it yet. My bf ejaculated in me on the 15th, 17th, 21st and again this morning. Along with that I’ve had a white milky discharge , Ive had headaches (I don’t usually have these often), my emotions are off the roof, I bled a little and i feel nauseous sometimes. I took 2 pregnancy test, one on feb 21st, and another on the 22nd and they were negative. Could I be pregnant?
