Peak day advice

I had HSG test on cd6, everything was normal. I usually peak around cd 22/23 but this cycle I think i peaked yesterday morning on cd 16. I usually test in the morning but didn’t get a chance to test until 4:30 last night. We had sex morning of peak day and did at home insemination this morning because we thought my peak came early. Any thought on this? Does my chart look like my peak came early?

Also, I’ve been having my typical ovulation cramping today, which also makes me believe I hit my peak.
