Ive been using opk's (2 diff kinds, twice a day) but am now on day 15 and have no sign of a positive yet.

Cycles have been a bit up and down since coming off bcp in october, but last cycle was exactly 28 days.

I expected to o by now and am beginning the paranoia!! What if i dont o this month? Do any of you guys normally o after day 15?

well i have a 26/27 length cycle and my OBGYN told me i should "O" @CD12,CD13...so i always bd starting CD11 to CD16 but i am on my 4 month ttc...so for the first time i bought a OPK this week and start to use it on wednesday and just this morning i got 2 really dark line on it and i am on CD12 if my cycle is 26 days long and CD11 if i was on a 27 days cycle.
OPK predict your ovulation 24 hours to 36 hours before it happen...
how long is your cycle average wishe?
you may just have not "O" yet.

i think you need to add 3 month of length cycle to get a average of your cycle.
that is what my obgyn told me if i was irregular.

Usually 14 days BEFORE next period. I was usually pretty regular (31 days) so just kept an eye on cervical mucus.

yeah, im keeping an eye on everything... and may well happen in next few days... just getting twitchy cause i started testing on day 7 and im getting fusstrated now We've bd'd at least every other day since cd7 and i just wanna know that its going to good use now.

You have been busy! As they say practice makes perfect, so sure you are not wasting time

In that case its 31days.... so o could be monday! Thats ages away!!

Go on www.askdramy
It works it out for you....I have a 29 day cycle and I had O pains yesterday, Mervs Mum recommended this site so just went on it for curiosity and it said that I should b O'ing yesterday...I cudn't believe how accurate it was considering I thought I should have O'ed days b4. So give it a whirl????

Here's some of the dust in the meantime....

if we're going average from last 3 she says monday
if we're going last cycle she says today

R u getting any twitches or O pains today????
