If your last period was 0ctober 24th and it come on yet November should i be worried?

It is possible to be pregnant even if your period has not yet arrived. Periods can be delayed for a variety of reasons, including stress, illness, and hormonal imbalances. If you have taken a pregnancy test and it is negative, it is possible that you are pregnant but the hCG levels are not high enough to be detected yet. It is also possible that you are not pregnant and your period is simply delayed. If you are concerned, you should talk to your doctor.
