Hi,
Thanks for posting in HCM.
I understand your concern.
Condoms when used properly should offer good protection against
pregnancy, although the failure rate is about 10 to 15%.
However, based on your description, it appears that your partner might not be pregnant and delay in
menstruation is not due to pregnancy. If she would have been pregnant, she should have all the signs and symptoms of pregnancy by now.
The reason for delay in getting periods could be probably due to
hormonal imbalance.
For evaluation of the cause, she needs to get her certain hormone levels in blood checked along with
ultrasound scan of the abdomen on consultation with Gynecologist.
According to the cause, appropriate treatment can be instituted.
Hope the information provided would be helpful.
All the best.
