I've irregular periods.
My obgynecologist found out that I have a right polycystic ovary last September.
I was told to take 5 Provera 10mg for 5days for the first time. I did.
A day after the last tablet, I had my menstruation.
But after a week, I was bleeding.
I went to my ob again and was advised that it was just normal.
It would usually last for 2-3 weeks and was prescribed with Iberet folic 500.
I was told to come back if the bleeding continues.
The bleeding stopped after the third week.
I got my next menstruation on Nov 26.
I'm still so busy at work and don't have time to go to my ob back.

We've been doing the deed like every 4-5 days and the last time that we had an unprotected sex was Jan 1.
We do the pull out method and we aren't sure if there was a leak.
I haven't had my menstruation until now.

I just did a pregnancy test today, Jan 4 and got a negative result.
Most of the time, I feel like I want to vomit but nothing comes out.
I've tried going to the bathroom if I would be able to vomit something, I did, 2 times.
I feel dizzy sometimes, like while not moving, I suddenly feel dizzy.
I haven't observed something different with my body so far.
This is the first time that I'm feeling this way.

I've tried not having my menstrual flow but I didn't feel anything. Unlike now.

Is it possible that I'm pregnant?

When would be the best time for me to do a pregnancy test?
Since I'm irregular, when would be the latest time that I'd do the test?
We would like to know the result the soonest if I am so that I can schedule an appointment with my ob.
