Curious....????

Im confused, So from Dec-Feb my periods were pretty normal ranging between 26-31 days well this month i didnt start bleeding till 42 day cycle (By My history reports putting me 4 days late). Before i started bleeding i was having what could be considered PMS symptoms or Pregnancy Symptoms, my breast were sore, bloating, constipation, acne, sweet tooth, dark blue veins in my breast which are still there. My husband and I use the "pull out method" sorry for all the info. I started bleeding Friday it started out light but by sat morning it was heavy i stopped bleeding last night (sunday) and since i stopped all those symptoms have gone away besides the veins in my breast. Im leaning more towards it just being a late period but im curious to know if anyone else has had this problem and come out pregnant. Thanks!!
