How accurate is fertility friend with ovulation?

[ardnaxela]

I'm so irritated because it looks like I'm out for this month if fertility friend is accurate about my ovulation date. I want to get a second opinion. Does it really look like I O'd on CD 9?

It's only as accurate as the information you give it. Did you have a positive OPK? You appear to have had the appropriate temperature spike at that time. FF does seem to heavily rely on temperature so if you are unsure if you're doing that properly then it could be off.

I did not have a positive opk but I just started testing yesterday. So it could have been positive and I missed it. My CM is watery still. It rarely ever gets EWCM. Why would my temperature stay down for three days if that's when I O'd? I just had a few uterine twinges if that means anything.
I've been taking femara on CDs 3-7. 2.5 mg. could that have affected my temp any?

I really don't know. I'm sorry. I see that your temp was down for a few days before, but it was consistently down, like right around the same temp. So the spike there around day 10 looks accurate to FF. Like I said, FF really heavily weights temperature information.
Generally you get the EWCM right there at ovulation. I'm not sure why FF is completely discounting that symptom.
I wish I could tell you if you ovulated! I'm sorry!

I agree with PP. I almost wanna bet once you put in a pos OPK it'll shift the ovulation day. But I'm not making any promises.

Just thought I'd let everyone know that my temp dropped and FF said they haven't detected ovulation!!
