TTC temp tracking

Clare

I ran out of LH test strips before my surge and I have loooong cycles. Normally I get my period 13 days after ovulation but I can't for the life of me identify ovulation on my temp chart this time. I'm on day 41 still BFN pregnancy tests and no AF. Any one care to interpret my temp graph for me? I don't think glow got the fertile Windsor right. The green plus marks where I think I might have ovulated based on my CM but it wasn't an actual LH test result. If I get AF I'll order more strips for next month. I'm 20months post partum for baby 1 and AF returned at 12months pp. Stopped mini pill last October so 4 months no pill and I'm on cycle 3 since then.
