So I went off bc beginning March got af 3/10/15 supposed to get first Af today (4/7/15) since coming off bc...did not come... baby danced once during fertile window...now I am experiencing weird symptoms I never have before... Could it be coming off the pill, getting af, or Pregnant? Had stomach cramping, constipation for a week, now strange pains around the breast area so confused? HELP!
