My husband and I made love five days after my last day of menstruation, around march 31 to april 2 . We were unprotected but he did a withdrawal. A week later, I experienced spotting. I did not think much as I was just starting abs work out consisting of 100 crunches, 50 legs up and 1 minute plank a day. My menstruation, although unpredictable, is expected April 20 to 25 (I had my period last month around 21 to 26). But right now, I am feeling breast tenderness beyond normal and when my breast is squeezed, watery discharge comes out. Just this morning I had leukorrhea. But aside from these, I don t feel anything like pregnant. I don t want to be pregnant yet. I have been fat for 5 years and just lost 9 kg last year september and just enjoying my body back... hope I am not pregnant... but, could I possibly be? and If so, can I still prevent it at this stage?
