View Full Version : Can the luteal phase change from month to month?

ie, can a woman ovulate at different times from one month to the next? The reason I ask is that DH and I DTD and used the withdrawal method (worked for us for 8 years prior to DS, I might add, then he only took one BD to conceive). We're not actively TTC#2, but not exactly avoiding pregnancy IYKWIM, we do want another at some point :yes:

I checked my cycle dates the next day and we had BD'd on about day 23 of the cycle, and if my luteal phase was 14 days, I would no longer have been fertile, according to an online fertility calculator.

The thing is, since my AF returned after a lovely 19 month break (still BFing DS), my cycles have been VERY regular, pretty much exactly 28 days, maybe the odd 29 day one. As of right now, I'm 2 days late for AF and no sign of her, apart from a bit of cramping about 4 or 5 days after we BD'd and right now I'm sitting here and can feel ever so slight period like 'feelings' (not like a cramp though, very very mild).

Has anyone ever conceived AFTER the time when they thought they were fertile?

the fertility window is about 5-7 days...

sperm can live in you for up to 5 days and an egg can be fertile for up to 2 days.

So there is opportunity to catch after ovulation

HOwever, if you bd's on day 24 of a 29 day cycle - i would have thought it was more unlikely

Thanks! It's probably just AF taking her time arriving, and unless I ovulated late in this cycle it's unlikely that I'm UTD. I would love it if I were pg, but it's probably wishful thinking :o

It is possible to ovulate more than once... or release more than one egg.
Apparently women can ovulate also during their lunar cycle. You'll have to google this as I don't know how it's figured out... not much help sorry!

When an old friend of mine was TTC she fell pregnant 2 days before AF was due , so anything is possible

:fingerscrossed: and goodluck

Your luteal phase (O to AF) should be fairly consistent. Its your follicular phase (AF to O) that can vary (for those of us who don't have a cycle set in stone).

Last month I Oed on CD18 and this month it was CD20, so I'm expecting a 33 day cycle instead of 31days. Hope this helps.
