On Estrogen levels after ovulation

[JustLooking_30]

When I start TTCing, it will be by IUI with frozen sperm and hence its absolutely essential that the timing be right.

I've been monitoring my natural cycles for the past few months, using BBTs, CM and the Clear Blue Easy Fertility monitor.

I've noticed a distinct pattern that repeats every cycle. I have 2 days of peak fertility (ie LH and estrogen high), and on the 3rd day, I STILL have a high fertility (= high estrogen only) reading. The 4th morning, estrogen levels fall back to 'low'. The temp rise is a bit ambiguous at this point but rises unarguably by the day after.

My question is this:- If you are registering high estrogen, that means you still have not ovulated right??

According to one source, women who ovulate within 24 hours of surge or following 48 hours ARE the outlyers, but they do exist :-) Wondering if I am one of them!

My quandary is whether to schedule my IUI at 33 hours or 48 hours post surge.

you can look at a good picture of the various levels during a cycle here

from what im looking at it seems pretty clear that estrogen rise is not as sharp of a rise and fall as LH , that might easily account for the extra day of the high estrogen level

not sure on the timing question beyond that, i would ask the IUI clinic, and consider if you can do 2 iui's a cycle or get a trigger shot to make the timing even more precise?

Hey adorkable, tanks for responding! I want to do this naturally as possible and right now all signs indicate that things are working nicely, want to avoid tinkering with it.

According to TYCOF, within a few hours of ovulation, estrogen levels are supposed to plummet and progesterone rises.

At 48 hours post surge detection, I'm still producing EWCM (teeny tiny bit), temps are in the preovulatory range and my CBEFM is showing me a high fertility reading.

See my chart, I think FF is going to predict that I ovulated 48 hours post surge, just like it did in the last cycle.

I think the signs, as I am reading them, point to ovulation taking place 48 hours post surge detection, but I want 2nd, 3rd, 4th and 5th opinions

Just a thought but how are you temping? Your temps are kind of crazy, like the cycle before you had a 94 degree reading...? You might want to try to temp vaginally or get a new therm and maybe you'll see a more clear pattern with your temps.

I was temping in the wrong place orally in my last cycles (along left upper gumline). Switched to below the tongue for this cycle, things don't fluctuate so much, and my temps are also in a far more normal range (its nearly 2 degrees higher at many points!).

I'm trying to avoid vaginal temping, I think things *finally* look ok in the last cycle right?

I'm not sure if this is of help, but wanted to offer it in case- the CBEFM is programed to automatically read one High day after your peaks, then to Low. As far ask I know, it isn't a measure of your hormones at all after it detects the peak- it goes on autopilot. (You may already know this, but just wanted to offer it in case that makes things clearer for you.) I've even heard of women stopping poas after the first peak, bc the following few days aren't really a measure of your hormone level.

I've also heard that the Peak reading is actually a measure that you WILL O i n the next 24 hours, not that it has already happened.

to me, the temp spike you have looks promising and lines up w/ your monitor readings.

Best of luck.

is this O date right?!?!

Thanks Babygrey, that was useful information!

So the FF software assigned me an ovulation date- don't know if it is that day, or the one after. Opinions needed please!
