Ovulation with no period

Since stopping the pill, I have failed to get my period.  I'm guessing it's just going to take a while to get back to regular, as I was always regular before going on the pill.  Someone on this mb said that without a period, one can't get pregnant, but I've read many sources saying that many people ovulate even though they hardly ever get their periods.  With that being said, I would love answers to the following questions:

1.  How do you track ovulation when you aren't getting your periods?  
2.  If the answer to tracking ovulation is ovulation predictor kits, when would I even use one?  I heard the kits only have a few pee sticks, so wouldn't I at least have to estimate approximately when I thought I would ovulate, and how to I do that without periods?

Now I just found conflicting information on the internet saying no period = no ovulation.  There are too many darn sources out there.  Anyone know for sure?

My sister got pregnant without a period.  I know they "say" you can't, but we know for a FACT that she did... she had a healthy lil baby boy!

My doc says you ovulate before getting a period - i have been on the pill for 5 years and for the past 9 months my periods have stopped - i am now 14weeks 2 days pregnant - I have been on the pill the entire time and had no period so definately possible!!!!

How did you know when you were ovulating if your periods were irregular?  Or did you just get lucky? :-D  It also seems like if periods aren't happening, it would take longer to find out you were pregnant, because usually the missed period is the first indication.

For 9 months on this new pill my periods were non existant. I had 7 days pill free but no withdrawal bleed.

I didnt ever expect to fall pregnant as i was on the pill and never missed a single one.

I didnt find out i was expecting until i had serious cramping at 6 and a half weeks and i decided to have the coil fitted! Only sign i had was extremely sore nipples but this went away.

Im 14 weeks 2 days accoding to last scan.

Biggest shock of my life and was unsure what to do (whether to keep the baby or not) but i am and i cant wait to meet my little hippo :)
