Hi Rollercoaster - I am doing my first natural FET at the moment and I know what you mean about being scared of missing ovulation. On the suggestion of someone else I started testing a couple of times a day just to be sure that I would catch it.

FYI I had a scan on Monday and a BT. My Follie was around 17mm and my BT was negative. I too felt like I was ovulating or at least close to it. I tested at home yesterday twice and both times were negative. I tested at home this morning and I got a positive. BT this morning also confirmed I am surging and will be ovulating tomorrow.

For your peace of mind there are 2 days that you can pick up on the surge - the day before and the day of ovulation.

Is there any way that you could get them to do a BT for you? My clinic does them every second day once your follie gets to a certain size. That way they are guaranteed of catching either the day of the surge or the day of ovulation.
