When will I O based on these OPKs?

[mrsmesx]

Not sure whether O would be today (CD15) or tomorrow based on these OPKs?
I have to have blood tests at certain points so I need to pin down my O date!

I would guesstimate Cd15

Same

Yep I agree, I have been using the strips along side the expensive clear blue & I always ovulate the day after my peak. Another good way to confirm is by temping as it shoots up after ovulation

Hard to say as each cycle it can vary 12-36hours after Peak. The only way is with BBT.

Thanks everyone for the responses. Here's my chart. Although my temp has gone up I'm really not convinced now at all.
Yesterday my CM was creamy so I did really think I O'd CD15 but my temps are telling a different story :(

What I have found with temping is that unless you are very consistent it’s not very reliable. For example, I set my alarm every morning the same time & take my temp as soon as my eyes open without sitting up. Are you being consistent with your method? This is what my chart looks like

also if you sleep with your mouth open this can affect the results. Vaginal temping has been said to be more accurate

Yeah I'm really consistent
I've just randomly had a load of EWCM too

So now I'm completely confused and just fed up now. I've ran out of OPKs too and ordered some more to arrive tomorrow but the last one I used this morning was definitely negative

Think I'll BD tonight just in case

If you can afford it maybe try the clear blue digitals. I use these & it tells you when you surge (flashing smily face) & then when you peak (static smily face) & then after the peak you ov 12-36 hours after. They are a bit expensive but worth it for the accuracy
