My partner and I have been trying for a baby and this time, for the first time my period is late. I do suffer from Polycystic Ovaries but this has not stopped my periods completely before. I had a gut feeling this month I would not have a period long before it was due so I took a test 2 days early which was negative, then a second 4 days later which was a bit confusing (Instead of a - or a + I got a T) so I took another 3 days later which was also negative. My period is now 3 weeks late, could I still be prgnant?

It is possible you are pregnant. Since you are 3 weeks late it is time you make a doctor's appointment for a blood test. If that is negative you need to find out why you are late. If it is positive, you need to schedule a prenatal appointment.

Is it possible that there could be no reason for being late. Just stress and things like that?

Yes, most definitely. Stress can cause a late or missed period.

I don't think it could be stress to be honest. My fiancé and I are having a few issues but they didn't come up until after I was already late. I can't even got to the doctors for another 2 weeks because my surgery is only open mon-fri and I work the same times but I will go asap. I'm just afraid of looking stupid if I'm not pregnant.

Hun, don't be afraid to look stupid. We have doctors because we don't know what is going on with our bodies. It is their job to find out. That's why they pay mega bucks to go to school and lots of years in school.

What would be "stupid" would be NOT going to the doctor and finding out later that something is wrong.

Whenever you question something about your health, it is important to get it checked out. That is why they are there.
