How to plan baby #2 when AF still hasn't returned?

[Celsie]

When I was 3 months PG with Caeleb, DH was diagnosed with testicular cancer. They removed one of his testicals and was he was given a couple rounds of chemo. We were told there was the possibility that it may make him infertile, so he some semen stored before the surgery.

Consequently, we don't know if DH is sterile or not. If he is, we'll go down the IVF path. Either way, we'd like to start to TTC some time in the new year. My problem is, AF hasn't returned yet and I'd like to start charting again for a few months before we start TTC again.

Can you chart when AF hasn't returned? Is there another method to tell where your body is at?
