for December AF came 12/9/16 I had intercourse during my ovulation week(we use the pullout method). Today AF is supposed to come again. 3DPO I started to experience very tender nipples. Now I am having a milky white discharge only when my finger was inserted. My nipples are still very tender, I feel bloated and gassy. Also the past 3 days or so everything I seem to eat gives me heartburn. Could this be signs of pregnancy? AF normally shows in the am but there's nothing so far. I am also having very mild cramps, not my normal AF cramps.
