I'm breastfeeding and after a year I am finally getting period back. Its been irregular, had three periods so far. I am getting symptoms l, metalic taste, nauseated, dizziness, sore nipples. I checked today, and it's come back as negative. But my periods haven't started yet, it wss around this time I started last time(five weeks) should I check again, or is it just late period. I should also say we are doing thr pull out method. I am using clear blue test no not cheap test, didn't do it in the morning though.
