I meant there were NO tears in the condom.
I don't think you are pregnant based on timing, condom and negative tests. Other reasons can make us late, stress, changes in routine, illness, weight gain or loss, slow thyroid, hormonal changes. If you don't get your period within 3 months from your last one, then see your doctor as docs want you to have a period at least once every three months. good luck (oh, and they can run blood work then to see what's going on with our hormones)
