When do you actually ovulate?

[Pipbin]

I am expecting my chart to show that O day was Monday. However my question is, when do ovulation actually occur?
Is it Sunday night? Monday day? Monday night? The thing is that we DTD on Thursday night and Monday night. And both of those were actually about 12.30 that night so I've put it down for AM.

I'm worried that I've missed it. I know that in two weeks time I'll know for sure but I was just wondering what your thought were.

Here is my chart for those who are interested www.fertilityfriend.com/home/pipbin

your current chart does not yet confirm ovulation. There needs to be a sustained temperature rise above your coverline for 3 days. I suspect however that your temp will stay up tomorrow and FF will then insert a vertical red line on CD18 (monday), as you had a +ve OPK on sunday, and you have had 2 consecutive higher temps. I think there is a section on FF on how to record SWI data, TBH I always put it down as pm if it was between lunch time and going to sleep, and am if it was between waking and lunch.

Who knows if you've missed it. If you really did have EWCM from day 11, the swi on thursday probably does count as sperm can live for up to 5 days in EWCM. FF does have an analyser that tells you how good your SWI timing had been. You don't need to have done it everyday to get a "good" score. Ideally it likes the day you ovulate, the day after, and 2 of the 3 days running up to ovulation. So if you SWI alternate days from day 10, then daily from the first positive OPK until FF confirms ovulation does give you the best possible chance. That would mean 8 shags for you this month (any extras just for fun). I think this works, though it is a lot of pressure, it does mean that you don't have to keep it up all month (so to speak). In fact, with you ovulating quite late, you could start on day 12. I ovulate on day 16, at started on day 10. I finally got pg on my 4th cycle after mc, and my charts months 1-3 were very wonky. Month 4 I had a lovely text book chart, followed my formula and hey presto! I caught.

You seem to have an adequate luteal phase. You just have to keep SWI! Good luck
