Hi, I've just seen this so maybe too late, but anyway...
It's pretty difficult to tell from what you're saying, and it's also very difficult to know what's normal in the first month or two of temping anyway - for some people, a rise of .2 indicates ovulation, others generally see a rise of .7 or .8. So unfortunately the first month or so is very much a 'wait and see' time...
It would be really helpful if we could see your temps as it's hard to imagine what the chart might look like - especially because you don't say what your temps were pre-CD10. From the sounds of it, you had exactly the same temp every day for a week, which is extremely unusual and suggests to me that there's a problem with your thermometer. Because you're giving temps to one decimal place, I suspect you're using a fever thermometer (a bog-standard thermometer) rather than a basal thermometer. Basal thermometers (BBTs) have a smaller range (if you had a fever temp, it would be off the scale), but they are much more accurate and measure to two decimal places. If you are going to chart, you need to get a BBT. You can buy them from Boots for around £10 or from eBay for around £4.
Register with an online charting software provider like Fertility Friend (follow the link in my sig...) then you can share your chart with us.
As for this month's temps, well... not knowing what the first ten days were, it's impossible to say. BUT if they were around 36.1 or below, then the rise to 36.6 on CD18 would suggest ovulation on CD17, HOWEVER you would need to see a temp in the higher range today as well to be sure. The EWCM would suggest that you have not ovulated, though. You really need to get an accurate thermometer and to show us all the info on a chart for us to be able to advise properly, I'm afraid - you don't say what CM you had before yesterday, if any, and it's possible that you didn't realise it was EWCM earlier. Also, are you temping at exactly the same time each day, and as soon as you wake, before you get up, go to the loo, have a drink, etc? If you temp an hour later than usual, that could easily account for higher temps.
I wouldn't get too stressed about the temps this month, but get yourself set up for next cycle (if there is one - FX there isn't!), and join the chartstalkers thread. We'll be able to help a lot more if we can see your info!

I only starting temp from CD10.
