When did I ovulate?

[Rainyshowers]

I've just started taking my bbt. This is my chart for this month. When did I ovulate? It says I am 3dpo but I think the chart has measured my coverline low as there are quite a few temperatures over it in the last few weeks. What do you think as I'm new to this?

My chart isn't loading but these are my temps:
Thu- 36.23
Fri- 36.34
Sat- 36.31
Sun- 36.38
Mon- 36.51
Tue- 36.66

My chart uploaded!

I would probably say you might have Ovd on CD18 as you have spotting there so possibly ovulation spotting, plus you might have an ovulation dip too if that is the case. If the CD20 temp was a little higher then I reckon FF would have picked up that CD18 was possible Ov day too.

However, there is a proper shift in temp past CD20 which is what you are meant to look out for and I know some people get the Ov BBT dip a couple days before Ov!

Do you know how long your luteal phase is? If you do, then you could always work backwards once AF turns up to pinpoint OV.

Keep at it for a few more cycles and hopefully you will see a pattern emerging (and get to know your luteal phase length if you don't already)
