This pregnancy is not as easy as one would think.
I lived in the UK for 3 years but that was 6 years ago and I wasn't trying to fall pregnant back then so not sure of what the availability of gynea visit is over there for you but perhaps you should try and make an appointmet to see one, and make it as close to CD10 or CD11 as possible.
If you get a scan (preferably an internal, they show more of what is going on then an external) you can hopefully see if you have a nice healthy folicle.
I have been diagnosed by two different gyneas with PCOS and the baby I unfotunately lost at 14weeks was concieved with AI.
I went to the gynea on CD10 and he was able to see a healthy folicle on the scan and I then went for AI on CD12 and fell pregnant.
Not sure if you have done a CD21 progesterone blood test yet, this is a good way to confirm if you have acutally ovulated. I have one booked for 12th October.
I agree with DaisyDuke, it is a good idea to gather as much info as you can. I have a different spreadsheet for calculating the days and a graph of my cycle lengths.
One more thing that I was told, but there are probably contridicting stories out there.
My gynea told me that you calulate ovulation more acurately if you count 14 days from the end
rather than from the start of
.
Good luck to you both.
