DPO Question

Lindsay • 28 🌈🌈💖 due 10/31/21!

In May, I had a BFP at 10DPO, which ended in a miscarriage. Currently trying again, on our second full cycle since the MC, and my chart is “possibly triphasic” according to Fertility Friend. I’m 10DPO today and still only getting BFNs.

Has anyone had a BFN at 10DPO but ended up getting a BFP a few days later? I know a triphasic chart doesn’t always mean pregnancy, but I’m impatient, and can’t wait to be pregnant with our rainbow 😬
