Hi, I had my last period starting 23rd Sept. I usually have a 30-day cycle.

My sex history this month is
- 9th and 10th Oct (with condoms)
- 23rd, 24th and 30th Oct, and 1st Nov (without protection at all)

Today is 4th Nov. On 2nd Nov I took a HPT and it was negative.

I am pretty worried because I haven't got my period until today, yet I do not have any pregnancy symptoms.

However it is worth mentioning that starting 5th Oct my university activities have been really stressing me up and I started to sleep late, as late as 2am. I have also gained some weight recently.

My appreciations to anyone who could provide me any advice.

When is your next period due? Are you regular?

It should come around 21st to 25th Oct. I am usually regular, although as you know regularity can be thrown off by stress and change in biological clock.

If you're late and a HPT was negative, most doctors will advise you to wait two more weeks. If your period still does not come, call the doctor.
