i think its just the periods are late irregular, could be pregnancy, take hpt to confirm , dont worry its just the irregular periods.
It's possible it could be pregnancy, but it's slim. There are a dozen reasons a period could be delayed, and even the most regular cycles can get thrown off. Some reasons would be stress, diet, weight gain/loss, late ovulation, no ovulation, hormonal imbalance and poor nutrition. Medicines and illness can also mess a cycle up. Take a pregnancy test with first morning urine and see what that shows, or make an appointment with a doctor to have blood work done.
