Temp spike 15DPO and BFN

Chelsea

So originally FF said I ovulated 2 days before it does now but I'm not convinced I've ovulated at all. At the same time, my temp has spiked but no AF. Testing daily all stark white BFNs. What is going on? It's CD78 but I'm still nursing. Currently taking Vitex and only nursing 3-4 times in 24 hours. Successfully got pregnant with #4 while breastfeeding #3. Test strips show the most recent, PreMom started my count over.
