Need some help with ovulation :/

[hunni12]

I usually have a 30 day cycle and my period was 8 days, now what I am trying to figure out is when am I going to ovulate. if I would have gotten my period on the regular day of 2/8 then I would ovulate on 2/24, but now that it's 8 days late when should I start using opks? I am going to go buy a 20 pack of opks tomorrow and a bbt.


Btw way this was the first time my cycle has been late like this.
