Well Usually I have normal and regular period, no period pains only mild cramps the day before am due.
My last (normal) period was on the 23rd of September which last for 6/7 days, but the period the month after that was so unusual it came on the 25 of October and last for 3 or 3 and a half days, The first day there was just light pink discharge and then it turn brown over night I started bleeding.

Two days after this I took 2 pregnancy test that both came out NEGATIVE.

Am still waiting for my period to show this month but ever since I notice these veins in my breast and they feel really tingly at times, my nipples are sore and around them I have these white small spots, I have been finding it so hard to get out of bed even when its 1pm in the after noon above all this my tummy have been so bloated I think I might have move up in jeans size.

When do you think I should take another pregnancy test
AM I EVEN PREGNANT?

If you miss your November period then take a test, otherwise you're not pregnant.

Are you using any birthcontrol/protection?

You've got a lot of "Could I be pregnant?" running through your head so you're picking at a lot of stuff that you would normally ignore and wondering if that's a symptom. The only symptom you would get at this stage of the game is a missed period. Which you got at the end of October. For your jeans/bloating, it is the holiday season or you're just gaining a little weight. It happens to the best of us. Which would also explain your boobs. I would have your breasts looked at for the spots though. The lethargy? You could be coming down with a sickness, or it's winter.

Calm down and wait until you miss a period. Then two weeks after take a test. I wouldn't be concerned at this point.
