Could be stress....I have had that happen before.
Have you been this late before? do you have reason to believe you could be pregnant?? My periods are werid sometimes, stress can sometimes make you very late, I was 10 days late a few months back, but it did come..
if i were to take an hpt again tomorrow, should i accept whatever the results may be and stop worrying?
i have never been this delayed. but my period doesnt come exactly when i expect it to. the days just keep on changing.
Could be a hormonal imbalance, stress, a cyst...etc. You may want to take another HPT in a day or two to be sure pregnancy's not the cause. We see lots of posts related to missing periods on here....happens to us all at some point I suppose. If you're really worried, see your gyno. Best wishes.
