Help BEING DROVE INSANE WITH SILLY Q'S

[Pol25]

Just read a similar post and trying to get prg again... My last period ended on the 2nd of Nov and usual my periods are regular but just recently hadn't had one since July up until Oct...long story... but anyhow came on in Oct and period ended the 2nd-ish of Nov. So when is my period next due??? I think somewhere near the 30th of Nov. Am I right?
And as for getting preggers your most fertile days are between 12 and 17... do you start count the days from the first day of you last period or the last day of your last period or your first, last period free day... if that makes sense???
PLEASE ITS DRIVING ME MAD!

You count from the first day of your last period! Goodluck.

Thank you !!!! Thank you !!!!
Any idea when I should be due on...?

you count from the first day of your period not the last. Mine are 4 weeks apart from beginning to beginning. I ovulate around day 12

when did you start?

I started on the 24th and it was just a little bloody discharge.. then on tues nothing (the 25th) then on Wed a little more blood, but certainly not the periods I was used too! Then thursday I had a light period then from Fri 28th up until monday 31st I was HEAVY! lasted until 2nd but really light then.
