Farfalla - I'm glad you and DH have had a row-free conversation about it all today. Do you feel a little better? I know it's still hard to know what to do though. I guess for a while it's just got to be SFF? I guess DH doesn't need to know when it's time to ov even if you do? Maybe if you have a little while with the pressure off, just SFF at the weekends or when you want to you might find you get some of the spark back into it? Then that might in turn mean you might be able to work up to some midweek SFF? The more you get the more you want or whatever 
Pomme I had a Duofertility monitor for a mere £500
. Honestly I'm not sure it was worth the money, although I did get pg
. Basically it just took my temps, but you wear a little sensor under your arm so it gets the temps for you after the right number of hours of sleep etc. then you sync the sensor with a reader and connect the reader to your computer and it uploads all the temp data. Then it basically does what fertility friend does and works out when you ov'd. In addition you get access to their 'fertility specialists' which is potentially helpful. They will look at the results of any tests you've had done, although they obviously aren't actually offering you any treatment. But for example if they looked at SA results they might say 'oh, you should perhaps try every 3 days instead of every other' or whatever. So they can offer advice. You can actually buy the monitor and then subscribe for the support service monthly I think and then the monitor is only £100 ish (?) but you do have to subscribe for the support at something like £40-£50 a month or something. Obv cheaper though if you get pg within a few months.
What I would say though, is that when we got it we were very desperate and looking hard at IVF so £500 didn't seem so bad in the context of several thousand.
Also I had never heard of mumsnet or fertility friend. In my opinion, i think you get nearly the same level of advice from
MN (I know technically we're not qualified but there's a lot of experience here) and I'm sure fertility friend does exactly the same, especially if you subscribe to the premium service.
Like fertility friend it would sometimes change its mind as to when I ovulated and did this extensively the cycle we got pg. to the extent that as they were telling me I must not have ov'd I was getting a BFP
.
Oh and the other thing was that it gives you a 'fertile window' to aim for. You have to SWI twice each cycle in that window for the money back guarantee to be valid. At first it just assumes that you'll ov mid cycle but it is supposed to 'learn your cycle'. We fell pg on cycle 3 so I can't comment on whether it ever did learn anything about me.
However, when changing its mind about when I may have ovulated, it also changed the fertile green window for when we should have been SWI-ing. However, it did this retrospectively! So it was a bit late to go back in time and shag at the time I should have done iyswim? Then that made me wonder whether they would try to stitch me up on the money back thing. When I asked them about it they said hat they recommend you shag every 2-3 days throughout your cycle anyway
. Kind of defeats the object of having something to predict your fertile window one would think
.
Umm, what else? Overall I'm not sure it was worth it. If I'm totally honest I thought for £500 it must do something more than just take my temps. I might have been expecting some sort of witch doctor magic 
. I was sold on the 'learning my cycle' and 'predicting my fertile window' but it wasn't as clever as I thought. I think you pay A LOT for the support services. On reflection I wish that I had perhaps got a CBFM and then taken my own temps to confirm ov. I also had a regular cycle so was fairly confident I was ov'ing. I was just fed up with having to shag all the time
.
Oh, and last thing, although we got pg while using it, I think this was a result of our HSG and improved SA. The monitor just hanged its mind about ov time and that almost made us stop SWI too early? Who knows.
Anyway, that was an essay if anyone was interested
.
Lots of hugs all round lovely ladies xxx
