When do you start 2ww…

[Mydogteddy]

From???

14 days before your next period is due.
How long are your cycles OP?

Around 25-27 days

I recommend using an app like Ovia or Flo to track your cycles.

To be certain you could track ovulation- ovulation tests (and optionally bbt). Otherwise it’s an estimate based on your usual cycle length, they are not guaranteed to be that every month but it’s likely good enough.

I Before I tracked opk and bbt I used my cervical mucus as the fertile window and then started the tww the day it ended. That does assume it’s predictable etc.

I count the TTW from after I ovulate. If I get an OPK peak at cycle day 15, I know I'll probably ovulate on cycle day 16 (can confirm with BBT testing) and then cycle day 17 would be 1 day post ovulation (DPO) and so on until my period arrives. My TTW tends to be 12 days rather than 14, being 2 weeks after the positive OPK.

Thanks guys
