Not feeling very positive

I don't think I'm pregnant. My period is due anytime from Monday - 3 days from now. I'm feeling bloated and my moods have been swinging over the last few days. I just don't think it's happened. For as long as I'm not in regular work, it's not an ideal time. So it's probably for the best if I'm right. I'm considering taking a month off the treatment, just to give me more time to get a job before trying again. But on the other hand, it's much more convenient to be going through the treatment while I'm not in full time work. It's a dilemma.
